I've noticed since TV Pack 2008 on Vista x86 and Windows 7 x86 that when I do not use the option to autostart Media Center from settings within it and instead use the HKLM Registry run key I often get an error.
Before TV Pack, this used to work 100%. After the WELCOME message on logon screen, the screen would fade out and up into Media Center with no Explorer to be seen.
On TV Pack or Win7 you have to use the option inside Media Center which puts up a Media Center splash screen and you see the start bar.
Seems to happen with Intel X3000 graphics and any Nvidia and ATI I have used. It does not give the error message EVERY time on system startup though.
The symptoms are the DirectX does not do the animated menu transistions and its jerkier movement. Exiting Media Center and running it again fixes it.
This happens on 100% clean machine with no antivirus even installed.
The message is complains about no suitable graphics card !!!
Microsoft this one is easy to reproduce, just put c:\windows\ehome\ehshell.exe into your HKLM RUN key and reboot.
Ay chance of fixing this for RTM ? It's been hanging around since TV Pack and I did report in the Windows 7 Beta feedback.
