you'll need the full version of powerdvd (se will do) or another dvd decoder.
Well, i have gone through several possible methods to fix my problem, and still nothing. i just installed home premium, OEM and it is unable to play dvds in the Media center or media player. i believe my ati drivers are fine, everything else seems to work with them, and i can watch the demo videos fine. i installed the trial version of powerdvd and it plays the dvd fine, but step over into microsoft's players, and nothing works. if in media center, i get a display error or something else is trying to play the dvd. if in media player, it says there is a problem with my coded, vid card, or dvd drive. i have even tried changing the default codec for the media center, to powerdvds, with nothing but a crash. can any one help me? could it be my dvd-rom?
