Just got the 16x Pioneer DVD from Mwave. Installed PowerDVD and watched Gladiator, great picture with no problems. Popped in Braveheart and after about 45 minutes the picture froze w sound looping. Had to do a hard reboot. Did the same thing twice more on the same movie, different parts. I am running Win2k, SP2 beta, Via 4.29 finals, Nvidia 7.52, Visiontec Geforce 2 GTS, Duron 700 not overclocked, Soundblaster Live w/o Liveware. Ideas?
