Hah, if only 7.3 would play ALL HD DVDs as you say...try running Terminator 2 Ultimate Edition with the German DTS track...PowerDVD will crash(see the German Cyberlink forum that apparently noone reads or also on the cinefacts.de forums). Other tracks will work. I'm still waiting for a patch to fix this. Needless to say, I'm not purchasing any upgrade as long as that isn't fixed. And yes I've mailed support and here are the five brilliant answers:
1)send dxdiag.txt and BD/HD advisor results ->done
2)this were very detailed reinstall instructions->useless as I'm not the only one with this problem but done none the less
3)see above
4)PowerDVD doesn't support Dual Displays in HD playback->useless, I only have one monitor and never mentioned I would be using two or more
5)request to send dxdiag and BD/HD advisor results
USELESS
So guys, what answer will I get next to my pending inquiry? I would guess the reinstall instructions and after that the dual display answer again? How hard can it be to fix this problem? Look what different the German track is from the others and then FIX IT! Come on guys, you can do better than to send me hillbilly answers as if I wouldn't know what I'm doing on my PC.
