Try doing the encode step by step with intermediate files.
Did it. And I disovered, that it is not mpeg2enc that crashes but the 
resample filter of transcode. Sorry for the wrong conclusion and thanks 
for the help.

 HI!

 Where can I found the release notes for new versions of mjpegtools (I
 did not find anything up to date in the source archive)? 

Yes, they need updating!

 With 1.6.1.92,
 timestamp in NTSC movies was wrong. This seems to be fixed in .93, but I
 was wondering.

Do you really mean timestamp? There was a rate control issue in .92

 With .93 and transcode, I got some warnings during encoding Decoder
 buffer running low: boosting overshoot gain!. Is this serious?

It is unclear: the relevant routine doesn't actually belong in that release 
(it crept in by accident via cvs backmerge).

Full log of mpeg2enc's output... (-v 1 or -v 2 ).  Crashing is pretty bad 
though - try to do each part of the transcode seperately rather than 
all-in-one go to isolate the possible sources of the crash.

Your environment: Distro, libc version, compiler version would help loads 
too...

Maybe it was that. Other tools showed the wrong length of the encoded movie.

As long as it does not mean anything goes bad... ;-)

Any hints on this? I am pretty new to this stuff under Linux and I am 
only just beginning to understand transcode, let alone what it does 
internally.

OK, I'll try to provide as much info as possible soon.

Thanks!

It's an AVI limit. There's openDML extensions to overcome this, but we
don't support them.

 Can you tell my something (good) about the future of the linux-marvel
 project? That list seems to be quite dead, but i would like to use my
 card with future kernels, as well. Can't you integrate the
 marvel driver into the unified iomega-myro-etc driver? The marvel
 also has a Zoran chip...

Well, I proposed that, but they weren't that interested, it seemed. It'd
be a lot of work. :(.

And, which seem to be overlooked time after time, if one doesn't mind lavrec 
splitting the capture into several files, one can always use a %d in the file 
name to avoid running into this limit.
