DVD SP - skipping m2v file
I'm trying to create a DVD from an NTSC DV file in FCP. The file length is 88mins, it contains no Motion files. It does contain rostrum shots which pan smoothly across artwork, created in DigiRostrum and output as NTSC DV .mov clips, then dropped into the timeline. I have output the whole movie to a self-contained .mov file, and then I'm compressing that file from FCP through Compressor, creating m2v files for the DVD. These files, when viewed directly with MPEG Streamclip, or whether viewed in the subsequently burned DVD (created in DVDSP), exhibit skipping, but only during those artwork rostrum shots. Not strictly true - there are some other shots where, for instance, a bus crosses frame, where the skipping also occurs, but it's difficult to spot there. This skipping is random. By that, I mean that it occurs in slightly different places in the timeline each time I play either the m2v file or the DVD, but principally confined to those rostrum shots. If I check the file frame by frame, there is no evidence of any frames being corrupted, or out of place. Every frame is where you would expect it to be to create a smooth move, and has no pixellation or other unwanted artefacts.
This behaviour is the same on all my Macs - a MacPro, a Macbook, and a G5. I've seen several discussions here going back a few years which all address DVD skipping, and come to the conclusion that the problem is with the media and the burn speed, but the problem I have is with the m2v file before I get to burn. I've tried putting compression markers every 10 frames into the suspect shots, but I get no different result. I've tried compressing at the three different DVD presets available in DVDSP, but again with no different result.
Can anyone explain this?
Many thanks.
