nevermind. i got it working. but to be honest, i dont really know whats changed. but to those of you out there that are having the same problems (if any) heres what ive got currently, and working: INSTALLED: Nvidia decoder. the latest klite codec pack. (originally got it because the sound levels on some dvd playback was quiet (and these forums told me that it could be an audio codec problem, and this was the best solution) (note: i made sure ffdshow didnt install) the ffdshow from http://www.gameex.net/Download/WrappersPlu...85/Default.aspx (the others posted above didnt seem to work? i tried all of them) the divx fix from http://www.gameex.net/Download/WrappersPlu...85/Default.aspx and in advanced config i have: -dvd decoder: NVIDIA -vrm9 enabled: YES -dvd uses FFDSHOW- NO. and for whatever reason, im now getting dvd previews (in the selection menu) back again. im pretty sure its just about getting a version of ffdshow that works with gameex. thanks for the help brian!
