Is this specifically an ION issue or a 9400 issue?
My Mythbox has a Gigabyte GA-E7AUM-DS2H motherboard. Its a "normal" PC core 2 duo motherboard with onboard nVidia 9400 graphics. Do I have the same problem?

Eeverything I've tried always plays back fine under MythTV, including direct rips of all my DVDs except for some reason my Pink Floyd "Pulse" DVD 2 disk set.

Under mythtv the audio is fine but it has (very) corrupted graphics: mostly random pink blocks etc instead of a picture. The same rip plays just fine under mplayer, VLC etc. I've always presumed that the DVD must be using some unusual encoding that is technically within the DVD spec but mythtv player doesn't (yet) implement. I've not yet figured out how to identify exactly the encoding used on a DVD so not really diagnosed it, but could it be the 9400+VDPAU problem?
