I have three "VCD ready" MPEG files that I want to demux, combine into one file, re-encode to MPEG2 to make one DVD rather than 3 VCDs. The problem is that when I demux the MPEGs, the resulting audio and video files have different durations. For example, when I open the original MPEG in Quicktime, it is 50:16. After Demuxing, the Audio is still 50:16, but the video is 50:13. Any thoughts? I have tried the "Add Scaled" routine in QT, but it does not allow me to do that with the mp1 file.

Any suggestions will be appreciated.
