I know it is possible to use the 360 HD DVD addon with a windows PC, but I'm encountering a problem....

When I load up PowerDVD (the version that lets you playback HD video), as soon as I hit "Play", the application crashes. There's no error messages, nothing. The process simply terminates. I can playback 1080p video from the hard drive no problem, so I don't think its an issue of low processor power. Anyone else encounter this?

Specs:
XP Media Center 2005
Intel Core 2 Duo
1 GB RAM
Some video card (can't remember)

This is a question that would probably be better asked in the HTPC forum of AVS -- they have a whole thread dedicated to PowerDVD and several other 360 add-on users as well. It will probably help them to track down the problem if you can find out specifically what video card you're using, since drivers are pretty crucial to good operation. Good luck.
