Recently I downloaded an Xvid. Within the download in contained two files, CD1 and CD2. The total file size was 1.37GB. I used VirtualDub to merge the two files together so that I could burn it to DVD. As normal, I took the Xvid and loaded it into NeroVision, hit start and let it encode and burn. Nero is my program of choice and I have always used it to burn Xvid, DivX, mpeg, SVCD's, etc. Its always worked. However, the files that I typically load are in the range of 600-800MB, therefore there is never a need for compression. This time when I loaded the 1.37GB file, NeroVision told me that the file was too big to fit onto a DVD-5 and if I would like to reduce the quality to fit onto the DVD-5. I selected yes and let it run as normal. When it was done I put it into my DVD player, the quality was perfect but the video and audio were off by a few MS. When played on my computer, the file is perfectly in sync. What is the problem? Is there anyway to fix this?
