I do not know if there ist a tool. Each file has a header and a end. So

glav won't seem to load for me. If I try, for example:
glav recorded-clip.avi
I get this:
++: **ERROR: [lavplay] Error initializing Audio: Audio task died.

When I record, I must select the 'read', rather than th

Ok. I noticed that for some chapters on the DVD, the average bitrate reported by mplex
was almost 50% of the max bit
I have a Grundig GDV-130 (a TYT / Scan 2000 clone) with DVD-Loader

Hello.
I am making a SVCD where the MP2 audio is encoded from
two different sources (one AC3 file and one OGG file).
How can I join the MP2 segments into a unique file for
multiplexing with the MPEG2 video stream?
Regards.

For the movie as a whole. Shorter scenes will, as you have seen,
run up against the limit and there's nothing "wrong" about that.
The guidline often is given as 20%

I'm not soure what you mean, but if you mean that line:
INFO: [mplex] Picture rate: 25.000 frames/sec
and
INFO: [mplex] No. Pictures: 5191
