I really don't uses the HTPC for DVD playback - (I use it for HDTV playback from my HiPix and as an audio jukebox.) but it does work with PowerDVD.
I image that if PowerDVD works that WinDVD should should work too.
___I thought I have seen you in the Creative newsgroups asking this as well â€¦ If I remember correctly, Namlemez had an XP Game Theater under Windows 2000 working correctly. He usually visits in spurts so possibly a quick E-mail could get you up and running. Given the AC97 Creative cards can use PowerDVD 3.0.xxxx or the upgraded VRX under Windows 2000, this may be something for you to use as well. The M-Audio cards pass-thru DD or DTS using either PowerDVD 2.55.0620 or WinDVD 2000 under Windows 2000. I would try PowerDVD 3.0.xxxx or the upgraded VRX as Dan has mentioned instead â€¦ Do you see a pattern developing?
___If you have not checked into the Hercules forum yet, I would highly recommend that you do this as well. There are some smart mods over there in regards to the various Hercules HW but unfortunately; their forum interface is trash. Hopefully they will be able to help you directly.
