I love Power DVD 9 - with my Gefore 8800 GTS I get awesome video on my HDTV (HDMI over DMI) - problem is no matter what I try it crashes in Win 7 x 64 RTM - It worked on the RC no problem - but I can't get it to work even after the latest Power DVD patches / different versions of Nvidia drivers but no luck; even in compatibility mode - it crashes on the video tab or when I play a video - audio reads as 2.0 and not 5.1
Nero Showtime works well, as does Media Player (although my 5.1 / 7.1 gets messed up, my front channel swaps with the center one in MP and MPC).
Latest codecs / drivers /etc. all installed.
Any ideas as to why this is happening?
