Green artifacts after manually muxing with Nandub

[CHiWuaN]

This is the second movie where this happens...

I just finished encoding a movie with GKnot, but I set the audio processing to "Disabled", since for an unknown reason, the movies were getting out of sync if I let GKnot handle it all by itself. After the movie was encoded, I encoded the audio using GKnot's audio encoding and then, I used Nandub to manually mux the video + audio.

The audio was in sync with the video, however, the final AVI file (A&V) shows a little bar on the left composed by green lines. This doesn't take up too much of the original movie (maybe 4 x movie height pixels), but still, this shouldn't be happening. This green lines do not appear on the "only video" version of the movie, they only show up after I add the audio.

I know the problem is not the video codec, since this has happened with 2 movies: one was DivX5 and the other one was Xvid.

I'm using all the latest software included in GKnot 0.28.8

Ideas, anyone?

Use VirtualDub Mod and see what happens........but I set the audio processing to "Disabled", since for an unknown reason, the movies were getting out of sync if I let GKnot handle it all by itself.

How are you demuxing audio from vob?

I used DVD2AVI to get the .AC3 files out from the VOBs.

I just tried to do it with VDubMod. This is what I did:

1. Opened the original video only file
2. Added a stream in VBR MP3 format. I selected "No" when asking me to rewrite the header. (if I select "Yes", the final AVI has audio out of sync)
3. Click on "Save as" while selecting "Direct stream copy" for the video.

The destination file still has the same green artifacts. However, I just found out that when last time I let GKnot mux the audio for me, no artifacts where there, but the audio wasn't in sync with the movie.

Oh, and for decoding I'm using the latest version of ffdShow.
