I stumbled across this website today: http://dvdfix.cjb.net/ I started wondering if this may be related to the trouble I was experiencing with my movie playback on my PC. I was having trouble with audio sync, most notably with theater tec. , but all others as well. I tried downloading all sorts of sync related programs then finally just gave up. Now I wonder if I found the solution. My system is p4 2.4 800fsb, 1 gig ram, ati rad aiw 9700. Should have run fine. Yes, I have office installed. What do you think, is this program my solution or will it make my system crap out?
