synching m2v and wav audio - strange problem

[ecc]

I am having a strange problem while synching up an m2v stream (renamed mpg) with wav audio in another language. using EditStudio. I've had success with this before on three other projects but with this one whenever I stop playback, the video jumps ahead while the audio stays at its current position.

The m2v was actually a composite of footage, pre-credits sequence from one source, credits from another, and body of the movie from the first source. I deinterlaced, resized, and slowed down the framerate to 23.976 on all of these. Then I opened up DGIndex, opened each of them in order and hit "save project and demux video" to make it stitch the three video streams together as a single m2v.

At first I though the problem with the video and audio was because I had the project settings on PAL so I changed the framerate to 23.976 and the video size to 720x480 but I still had the problem. Then I put the m2v into DGPulldown thinking it had an issue with the framerate (since some low price NLE's still don't handle 23.976) and flagged it for 29.976 but I still have the same issue. On the previous projects, I did the synching when both the video and audio were still at PAL 25fps and then encoded the video and changed the audio with BeLight.

The credit sequence came from a DVD VOB that I demuxed while the other parts of the film came from an AVI that I converted to an m2v with HcEncGUI so that it matched the size and framerate of the DVD-sourced portion. The AVI had its key frames pretty broadly placed but HCEnc's GOP setting was at 15 which seems like it should be sufficient for NTSC. Are there any special measures I should have taken when converting the AVI to m2v?

I'm putting the question here because EditStudio's forums are down but also I'd like to know if this is an editing software problem or something that people have run into with other programs with either the audio or the video.

Another thing is that the m2v video is reading as four minutes shorter than it really is. The other projects I did, I synched when they were still in PAL but I cannot do that here because that would mean resizing the 2 parts of the AVI for PAL 16:9 and the m2v portion as 16:9 and encoding each part as an m2v, stitching them together, synching them, and then re-encoding the encoded (and partially reencoded m2v) and I've been told that MPEG2 degrades faster than some video formats.

I think it would be safer to work on a real MPEG program stream.
Multiplex the .m2v into an .mpg container and try again.

Can you mux an m2v into an mpg without audio or create a silent audio track corresponding to the length of the m2v?

i'd try to fix it by rewriting the gop timecode in the m2v. maybe use restream.

[Midzuki]

Yes, you can create a MPG that contains only video.
No need for a dummy audio track.
Try aedipuss's suggestion if the .mpg container
does not solve your problem.

Thanks. I'll try them.

Restream worked. Thanks. The one muxer I have with a GUI Imago (I know DVDAuthorGUI has some muxers in its program files but I haven't looked at them) would not allow me to procede without picking an ac3 file.
