Thanks to your email I finally got ds.jar - that was the
tool I missed.

I think of two tools.
The one is fast, based on GOP - limits and the first
few pictures after each split are bad.

GOPchop

 gopchop.sourceforge.net

The second is great but time-consuming: transcode
(On a 2GHz-Athlon it demuxes about 14 frames/sec)
  www.theorie.physik.uni-goettingen.de/~ostreich/transcode/

With transcode you can create avi-files conforming to the
mjpegtools. You can cut, paste, split....

Then you have to reencode this avifiles or the edit.lists.

The options for transcode that work for me are:

transcode -N 0x1 -i your_mpeg-file -y mjpeg -k -z -t7000,your_output_name

This will create avi-files with a length of roughly 1.7 Giga.

Since the avi-files you create this way have next to no noise you
need only few options for mpeg2enc - and no yuvdenoise.

Wolfgang
