ok i got me season 1 friends on dvd. and i cant get it to play on my computer. at first i wasnt able to get anything from it. i tryed powerdvd xp 4.0 and i'm getting error code 80070057 all the time. checked out their web site and there's nothing for that error. i tryed windows media player which kept saying that it's invalid or something. then i tryed player that was on cd and it said missing dvd decoder. i have installed everything from nimo pack and now i kinda get terrible ,slow and braking up sound when i run it in wmp and i notice that screen changes to slightly different background which should mean that movie is stating but i dont see anything, plus whole system just starting to freez up. i have compaq dvd-rom sd-612B, 196mb ram, riva tnt 2 model64/model 64 pro with 40.72_win2kxp drivers. what's the problem here??
