I hit the very same problem a couple of weeks ago when I installed Windows 7 64-bit on my HTPC where I previously had Vista 32-bit installed. I use a Soundgraph iMON VFD, a 16x2 character display. It used to nicely display all the media centre information using FrontView then, when I installed Windows 7, it became completely useless.
I then spotted that the manufacturers had released a new version of the IMON Manager software supporting Windows 7 (32 and 64-bit) which can be used to control the display. (It also contains the VFD's drivers.) I had not previously used this application because FrontView was much better for using with Media Center. Having installed this new version, it hasn't changed the situation with FrontView but it does seem to have added the ability to display information from Media Center to the iMON application. I now have IMON installed (FrontView uninstalled) and it will display all the necessary information from MC. It has a few annoying 'quirks', like not picking up on the fact that you've changed from playing one recorded show to another (unless you stop the first one before starting the next one), and it is not as configurable as FrontView was (you can't even stop it scrolling!) but it's better than nothing.
I realise that this probably won't help the OP as he has a different display type but it may help someone else who hit the same problem with an iMON display.
The other thing I noticed is that the settings for displaying media centre information are called 'Frontview' and it looks like this is completely integrated into the iMON application. Maybe they have taken over the rights to Frontview.
