I have mpeg films on my pc and have tried to use Nerovision and Movie Factory 2 to get them onto dvd-r. They are big files so by reducing the video bitrate i can get each film small enough to fit. Neorvision and Movie Factory dont report any errors and in the morning after encoding all night I get the message that the process finished ok. But when I try to play them I only have half of the film on the disc. I am using XP with NTFS. I have a P4. My harddrive is 120g and i have 1/2 gig of ram.Can anyone tell me why this happens?
