I use mjpeg 1.6.1, the command I alreday gives several times, the filesizes
are a lots different from time to time, here:
-rw-r--r-- 1 greg greg 181M Jan 5 12:19 /video2/001.mp2

Because, I use this to create a DVD:
ifogen -o /video2/tmp/VIDEO_TS/VTS "mpeg_files"
tocgen /video2/tmp/VIDEO_TS
And if the mpeg files are smaller I got more chapters ;-)
If you know other way to make DVD under linux, I would enjoy to know
about that way, and I like to have some chapters in my DVD (made with
recordings from VDR).
Thank you very much for all help, and please keep CC to me as I am not
on this ml ;-)
Have a great day,
Grégoire
