Help merging You-Tube video files

It seems quite straighforward but I'm getting an unusable result.

I get the warning about H.264 B-frames.  If I tell it no the result stutters horribly.  If I tell it yes the *VIDEO* is fine but the audio is running too fast.  This is a simple merge with no re-encoding, since the audio data itself isn't being altered I would think this means it's being somehow marked with the wrong play rate.

Why??

(One thought--the files are PAL, 25 frames/sec.  While I didn't try to time the audio error I wouldn't be surprised to learn it was running at 30/25.)

Yamb+MP4box might work better if you just want to join the videos.

AVIdemux 2.6 does handle audio desync better, so you might want to try it.
I am away between 15th of May - 15th of June. (yes, I am playing D3)

Yamb doesn't seem to understand .flv files at all.  2.6 didn't give me the H.264 B-frame warning and it seems to have produced a working file.

Thanks.

It's back and this time the 2.6 version is even worse.

The video simply doesn't work when it's merged with either the beta or release versions.

I think the same person did the original encoding, they are again from YouTube but now they are HD video with a .mp4 extension.
