I had been been using only ATSC channels for 6 months, but Friday morning 3 were not working.   My TVs and converter boxes all work fine, but not VMC.  Where can I find current data on virtual vs physical channels?  The ATSCchannels.xml file has the physical vs virtual channels as they were defined months last September.  Has something changed in the assignments?  I lost channels 7, 13, and 50. 

I have a Haupphauge 2250 tuner and VMC used to find 1 analog and 2 digital tuners.  Now it doesn't find the analog tuner, so my VMC FM radio won't work anymore.  Maybe because no station is transmitting analog now?

This stinks.

I don't know your area, but channels across the US have been changing frequencies throughout the day.

Will show you the pre and post transition frequencies.


In Phoenix, several stations changed frequencies at 12:01AM midnight, another at 8:30AM and the last few are going on right now. We woke up to no TVs picking up those channels and having to rescan. I'll have to rescan tomorrow because the last ones will be done by midnight tonight.

I am expecting the guide to be working properly tomorrow. I'll pull an update manually tomorrow and that should realign the frequencies as well.

edit: I have also have a 2250 - FM works fine in Phoenix (just tested) - radio is still broadcasting in analog, or all our cars would have issues...

7, 13 and 50? Washington D.C./Baltimore? WJLA, WJZ and WCDW? If so, yes, those three channels (and more) have changed the frequency that they broadcast on as of yesterday around noon.

Unfortunately, Microsoft/Zap2It are behind the 8-ball and haven't updated the guide to indicate the proper new physical channels yet (as of 12:33am EDT).  I added the changed channels manually until such time as the Guide has been caught up, which I'm hoping is any minute now.

If you are indeed in Baltimore/D.C., here are the channels you can likely fix manually until MS/Zap2It catches up to us:

WMAR-DT 2.1 (Baltimore) --> Physical Channel UHF 38 (was UHF 52)
WJLA-DT 7.1 (Washington) --> Physical Channel VHF 7 (was UHF 39)
WUSA-DT 9.1 (Washington) --> Physical Channel VHF 9 (was UHF 34)
WBAL-DT 11.1 (Baltimore) --> Physical Channel VHF 11 (was UHF 59)
WJZ-DT 13.1 (Baltimore) --> Physical Channel VHF 13 (was UHF 38)
WNVT-DT 30.1-30.5 (Washington) --> Physical Channel 30
WNVC-DT 30.6-30.10 (Washington) --> Physical Channel UHF 24 (was off the air)
WDCW-DT 50.1 (Washington) --> Physical Channel UHF 50 (was UHF 51)
WPXW-DT 66.1 (Washington) --> Physical Channel UHF 34 (was UHF 43)

And there might be even more depending on where you actually are (I'm in Howard County MD).  Hope this helps, and apologies if the 7/13/50 was just a coincidence and has nothing to do with Baltimore/D.C. at all ...

djp952,

How do I manually fix the physical channel numbers?

Ditto here.     Item 1 below is my big deal right now.

1.  I have 2 tuners, and all stations were fine yesterday.   Now I cannot get 2 stations (ABC affiliate and CBS affiliate) on WMC even though I CAN get those channels using the tuners in "native" mode--that is, with their own software.

2. Also, I manually added the sub-channels.   When will the GUIDE provide listings for these?   Listings are available on other guides?

3.  My local NBC affiliate is transmitting analog (just a message about the Digital transmission) and I am receiving this on the tuners, but not on WMC, this is not a biggie, of course.

 

 

No, not coincidence.   Having same problem (now I am getting Ch. 50, but still not Ch 9 and Ch. 7.   How do you do the manual change?

I am in Washington, DC.

DC/Baltimore market here.

I used the principles in this thread to tune in WDCW (Channel 50).

It's been a while since I haven't had TV Pack, which is totally different, but if I recall ... if you manually edit the atscchannels.xml file and then make it read-only, that will work.  Of course, the downside to this is that when the Guide is fixed (mine still isn't), you won't get the changes, but if it's all set up properly, I suppose you don't need them!  [With TV Pack/Win7, you can manually add everything through Media Center itself and even associate the proper guide listings with the channels, it's nice]

Here's my channel list with the corresponding physical frequencies as well.  Hopefully it will come in handy for you guys to sort out the issues.  Sorry I don't have any non-TV Pack PCs left to just make an atscchannels.xml replacement for you.

Hey walkabt!

I too live in the Phoenix area and I am still having ATSC woes. You seemed pretty confident about getting it to work. What are you doing to make it work then?

I have tried:

• pulling new guides.
• completely redoing my "Set Up TV Signal" (hoping that it would actually do a scan instead of relying on some cached data).
• someone on this site suggested manually changing atscchannels.xml and making it read-only and pulling a new guide.

Any other suggestions would be great!

Thanks,
Jim

Just wokeup and updated the guide data. Now shows 6/9/2009, which was better than the 6/5/2009 data it has been stuck with since the 5th.

Currently rescanning, the 2250 cards take the longest to scan - 2 seconds when I just had the 1600s and HD Homeruns setup, added one 2250 and the process takes 10 minutes. If that does not work (sounds like a no from everyone else) then I will do the ATSCprefs.xml work around.

JimF - the workaround is to manually update the ATSCprefs.xml file with the correct data.

My gut feeling tells me, seeing posts this morning, that several at Microsoft are working on this today (or at least typing in from home) trying to help. Hopefully we will back to normal soon.

Vista Media Center found only the 6 digital tuners today, no analog on either the 1600s or the 2250 so that was a nice surprise (never used them and have to manually disable when they show up), normally it shows 6 digital, 4 analog (registry adjustment to get them all to work).

The guide was still wrong (as before), did the adjustment - works now.

Thanks walkabt,

I have followed those instructions and now it seems everything (except one channel I don't care about) is now working.  I now remember doing this back when our PBS station switched a couple of months ago.

I guess I was hoping that for a transition this big, that Microsoft would not have resorted to making every user hack their media centers manually. This really should have been a no-brainer. In fact, I noticed during this "exercise" that our PBS station still is not updated correctly in the atscchannels.xml and they converted a month or two ago!

Oh well...

Thanks again,
Jim

thanks for info now working great and can record now

Where do you go in Win7 to make the channel -> frequency reassignments? I can't seem to find it.

Edit: Nevermind, I found it in this thread:
http://thegreenbutton.com/forums/thread/340770.aspx
I was trying to change it, turns out I just need to add a new one.

Yes, PBS switched over in April and was still showing the wrong frequency, but based on comments from AVSforum.com a while back that is because the station is still broadcasting the wrong frequency on the PSIP data (or something else like that) and that throws off Media Center.
