Well, it seems I am joining the crowd too.
I had 8 Ultra for some time now and it still works ok.
Recently purchased 9 ultra upgrade and having same problems as most of you guys here.
Audio combos in settings are empty and if I click on Video settings or try to play something app crashes and Vista gives me this message:

Any hope, or is it time to go WinDVD ?
