i have an afrrey 10x DVD, 10ghz athlon, 256mb ram, 40gig hdd. The DVD drive came with WinDVD2000. windvd came with some trailers, im not sure what format they are in, however, in windows 2000 when i looped it for about 30 mins, the picture got all blue and grainy, and an error popped up saying that i was out of virtual memory, also after about 2 plays, it stopped reading from the hard drive and the dvd rom, but the movie contiuned to play. In windows 98, it didnt do this, i could loop iat for 1 hour, and it would still be clear, no error, and it would stll read from the hard drive and the dvd rom. What is going on??
