There's no place like HomeGroup...There's no place like HomeGroup...

What is HomeGroup?

HomeGroup is a new feature in Windows 7 that allows multiple computers running Windows 7 to seamlessly share documents, pictures, music, media and printers. Windows 7 Media Center (7MC) has tapped into this new feature to provide a smoother experience for sharing media between Windows 7 computers. While users can access pictures and music through W7MC within the HomeGroup, I am going to focus on sharing recorded television content.

My friend Sean knows that I am on the Media Center team and asked whether he should consider upgrading to 7MC. He has a Media Center computer set up in his den, a HTPC (Home Theater PC) in his living room, and a laptop which he uses frequently for his business trips. He told me he has always wanted to install a television in his bedroom but his wife is adamant that that is not going to happen.

Since he still wants to watch television in bed, I suggested that he consider using HomeGroup. With 7MC, he can lie on his bed and use his laptop to watch the television content previously recorded on his HTPC in his living room. Sean works on his laptop in bed all the time, so he was really excited at my proposal. Also, since he travels a lot for work, I told him he can use 7MC to easily browse and copy his favorite shows onto his laptop; to watch them later on his long plane rides.

How do I Setup HomeGroup?

Before you setup a HomeGroup, make sure you have the computers networked together with a router or similar device. Setting up HomeGroup is rather straight-forward. In fact, you might have already set it up when you first installed Windows 7.

If you are installing Windows 7, be sure to choose ‘Home network’ in the Set Network Location dialog, as this is the option that will guide you through the HomeGroup setup. After you choose the ‘Home network’ network location, make sure that the Pictures, Music and Videos options are checked.

  • If a HomeGroup has not already been set up, a password will be generated for you. You will use this password to setup your other Windows 7 computers to this HomeGroup, so write it down.
  • On the other hand, if you have previously created a HomeGroup on your network, you will be asked to join that HomeGroup and be prompted to enter the HomeGroup password.

If you have forgotten the password, or would like to change the generated password to something easier to remember, select ‘Control Panel’ from your ‘Start Menu,’ and select Choose homegroup and sharing options. In the HomeGroup Control Panel that appears, you can view/print the HomeGroup password, change the password, manage the content you wish to share in the HomeGroup, or leave the HomeGroup entirely.

It is interesting to note that HomeGroups are attached to home network locations. While you can only be part of one HomeGroup at a time, you can also leave and join other HomeGroups. For example, if a student has a HomeGroup setup in her dorm room, when she visits her parents, she can leave her HomeGroup and join their HomeGroup instead, allowing her to easily share her photos on the HTPC setup in the living room.

How Can I use HomeGroup within Media Center?

Once your Windows 7 computers are setup in the HomeGroup, you can access the different galleries (Music, Pictures, and Recorded TV) on any computer, from any computer within the HomeGroup. For example, if my friend Sean wants to access the Recorded TV content on his living room PC, he simply navigates to the Recorded TV gallery on his laptop, selects the shared pivot, and then selects the computer by its name (in this case pc-livingroom).

mc2

Picking pc-livingroom in the shared pivot takes him into the Recorded TV gallery of the remote computer in the living room. The gallery looks almost identical to the host computer’s; so how do you tell which gallery you are at? If you look at the top-right corner of the gallery, you will notice the computer name, which tells you which Recorded TV gallery you are currently browsing in.

Once you are in the remote computer’s Recorded TV gallery, you can sort the recordings by original air date, or group them by title using the different pivots, like you were doing before on the host computer. If you select a recording, the details page will appear and you may notice slight differences in the commands available to remote content.

mc3The play button will stream the show to your host Windows 7 Media Center. Like your host Media Center, not only can you play and pause the remote content, you can also rewind, fast-forward, skip-forward, and skip-backward. This streaming enables my friend Sean to watch his recordings in bed, while not putting his marriage in jeopardy. It is important to note that if the content is copy-protected (DRM) you will not be able to playback the content. Such content is denoted with a warning icon on the thumbnail

Besides playing the content, you can also use 7MC to navigate and copy the non-DRM content over to the host computer for later viewing. This works well for Sean as he likes to catch up on episodes of his favorite series on those long plane rides. Copying the content is as easy as clicking the make a copy button. If you accidentally clicked on the make a copy button, you can cancel the copying by clicking on the Stop button on the Copying Remote Content dialog. If you click the OK button, the copying will occur in the background.

TIP!

You can queue-copy a couple of recordings by dismissing the Copying Remote Content dialog, navigate to another recording and make a copy of that content while the first show is still being copied in the background. The second show will start the copying process once the first show has completed copying. Here is another tip for you: let’s say you started copying a really long program, dismissed the Copying Remote Content dialog, and wanted to abort the copying process, you can still do this by clicking on the make a copy button for that program and then clicking on the Stop button of the dialog that appears. This will terminate the copying for that particular program.

If you wish to return back to the host computer’s Recorded TV gallery, go back to the shared pivot and select recorded TV. You can also choose all computers to see all the recorded content in the HomeGroup. Similarly, you can access Pictures, Music and Video using the shared pivot in their respective galleries.

Why Is There No Delete Button?

You might notice that there is no Delete button on the details page for the remote content. During the design phase, we debated long and hard over this, but finally decided that we need to honor the fact that the content is on another computer and we should not delete it unless we are on that computer. Media Center assumes that content recorded on Bob’s computer belongs to Bob, and Sally, who is watching the show via HomeGroup, should not be allowed to delete the content since we cannot be sure if Bob wants that program deleted from his computer or not.

What Are These Library Files I Hear About?

Windows 7 has a new file-type called Library (.library-ms) which, like the name suggests, is a file that aggregates similar contents which may be located in various file locations. For example, if you keep your pictures in many different locations (say in C:\PublicPhotos\, E:\PrivatePhotos\, C:\FamilyPhotos\, and so on); you can add these various locations to the Photo library file. When you access that Photo library in Windows Explorer, you will be presented with all the photos, but they will be in one “place.”

Recorded TV content is no exception. The Recorded TV Library file is located at C:\Users\Public\Libraries\ but you can also access it through the navigation pane of Windows Explorer. When you click on the Recorded TV icon in the navigation pane, all your recorded content will display in the main window of Windows Explorer.

To manage the folders of this library, click on the ‘location’ link above the folders in the main window of Windows Explorer. The Recorded TV Libraries Location dialog that appears is where you can add or remove a folder to the library. When you add a new folder to this library, not only will the contents of that folder appear in this library in Windows Explorer, the recorded contents of the newly added folder will also become visible in the Recorded TV gallery in Media Center.

You may have noticed that there are slight differences in how Pictures and Music are presented in 7MC and HomeGroup, as compared with Recorded TV. This is because Recorded TV has always been machine-based, while Pictures and Music are user-based. This is also the reason why parental controls for television content are tied to the machine instead of the user. So while there may be several Photo libraries and Music libraries on one machine, depending on the number of users on that machine, there is only one Recorded TV library file per machine.

Where can I read more about HomeGroup?

I hope you enjoyed this overview article on Media Center and HomeGroup. Try setting up your own HomeGroup and feel free to comment below to let us know how you use HomeGroup with Media Center. I also encourage you to read more about HomeGroup especially the two articles below.

How do I TURN OFF the Shared pivot, for those of us who aren't using HomeGroup but other Microsoft products like Windows Home Server?

Well I know for me, I disable ipv6, the homegroup services, and disable offline files from the group policy editor.

I still haven't "gotten the feel" for the appropriate use of homegroups in my house; and, until I do--the WAF doesn't take that learning curve into account!  :)  So, for now, it's as stated above!

Does joining a Homegroup still quietly prevent "idle to sleep"?

One of the first questions you should have asked Sean was:  "Do you use CableCard?"  If so, you are screwed and home group doesn't work for you.

I have over 2k invested in my cablecard setup and I cant even use this feature, great!

Copy-protected content is not supported. However, non-premium content recorded on the ATI Digital Cable tuner can still be viewed over homegroup.

Incidentally, as some of you may have heard, Seattle had an amazingly hot summer last week. Most of my television content is recorded on my living room PC. Unfortunately I only have an air conditioning unit in my other bedroom that does not have a television. Luckily for me, I was still able to watch my recorded content through Homegroup on my laptop.

If you have an interesting story on how you use HomeGroup with Media Center, we would love to hear from you as well.

Not being able to delete the content remotely doesn't seem right. Ability to delete should be based on user permissions rather than on what machine the content comes from. If I prefer to give everyone a right to delete recorded TV shows, everyone who accessese it via HomeGroup should be able to do so and have Delete button for that. If I would rather make it read-only than I agree there shouldn't be a Delete button.

I wonder if WHS is going to be well integrated with HomeGroup?

So I can share non-DRM content through HomeGroup... what's the big deal here?  Can't I already do that?

What about a shared guide/scheduled recordings being done on any available tuner across the network, streaming live content between the computers, syncronized viewing across a HomeGroup... and as many others have already posted, where is the CableCARD support for the sharing?  

Sorry to be so negative, but I was hoping for some new innovations for Media Center in Windows 7, not just a little more gloss on the interface.

ShinyDiscoBall: So, basically unless you work for Microsoft and thus have access to the ATI firmware that enables non-premium content to be recorded as unprotected you are suggesting people pull their CableCARD out of the ATI tuner and reconfigure their TV signal for unencrypted QAM, and then reconfigure again when they want to take full advantage of the rest of their cable package?

Here's what I'm hearing:

That upon launch, the appropriate drivers will be released that enable the ATI DCTs to DRM only premium content (ie., HBO movies), and that the rest of basic cable (even when recorded via DCT) will not be DRM'd.

This analysis is a result of pulling all the various threads together I've read over the months.  It would have been nice if the author would have better defined the DRM situation, as one would think that those who invested the most in WMC would like to hear how they're being treated.

Now if there were only some way to remove the DRM from existing recordings of non-premium content, so I could do a clean install of Win7 and still maintain my existing recorded TV library.

Chris,

Once again - Love the post...  exactly what I was thinking too!!

Jon,

I sure hope you're right...  This firmware has been rumored for a very, very long time....  Starting to wonder if it went the way of the Dodo and the DirecTV tuner.

htolino,

Good point man....  Wonder if that will even be possible?  Probably not...  :-(

JonDeutsch said:

FSUGrad,

Well, I presume I'm right since Christian Tan himself is already doing it!  I hope MSFT's roll-out strategy isn't limited to MSFT!  That would seem a bit insular.

Chris - Moderator said:

I'm not going to really doubt the firmware will launch at some point (well, maybe.  If I was AMD I'd have little interest in OCUR considering major OEMs have gotten out of the business), but you have to remember this firmware was supposed to be released with the TV Pack!

FSUGrad1999 said:

Yea, the one thing I wanted to be able to do was create a share where my recordings are, and watch them on my laptop outside on my deck by my pool...  or even liveTV...  neither of which I can do with VMC...

Well, I can install the HDHomerun channel util and that little video player that comes with it and watch live unencrypted QAM I suppose...  well, whatever my wireless G network will handle...

Anyway, that was one thing I didn't research very well, and was let down about...  And then I guess when I heard the rumors about softsled in Win7, I got excited again thinking that I would be able to do it on the next version of Windows...  only to find out, not really... once again, back to where I was...  ahhhh, the ups and downs that is MC...  :0)

Hi Christian,

Appreciate the post. I had been wondering how to use the Shared menu option in Recorded TV for a while but never really got around to looking into it until I stumbled on your blog.

Can you shed any light on the following thread? Several of us seem to be experiencing some sort of Homegroup bug?

thegreenbutton.com/.../76891.aspx

Thanks!
