I have already some hints to problems. Most testing so far I did with streams
from the same source (MTV2 Europe). For those, DVBCUT works rather stable.
But I found it segfaulting when taking video from another source (German TV
station ARD, for example). The point is, that the way the streams are
constructed seems to differ a little. Somehow I have implicit assumptions in
my code that the streams look like the ones from MTV2 ;)
May also depend on the source. I have cut streams from ARD successfully,
but I'm using DVB-T. I assume that you use DVB-S or maybe DVB-C (because
there's no MTV2 in the DVB-T channel list).
It may also be a size issue. DVB-T uses lower bitrates, and the
resulting files are rather small (typically 1 GB/h).
Just for the record: do you use a 32- or 64-bit version of dvbcut?

Yesterday and today I worked on this problem, and implemented my own MPEG
multiplexer inside DVBCUT to replace libavformat. So far it works quite well,
for example it solves one "problem" (well, I don't know if it is really a
problem): dvbreplex complains about inconsistent PTS and DTS when reading a
file created with DVBCUT. But since the same messages appear when running
dvbreplex on a FFMPEG generated file, the origin of this oddity is in
libavformat.
My new multiplexer works fine so far, at least dvbreplex does not complain,
and mplayer and xine play the output with no problems.
Xine isn't picky. It plays most streams, including corrupted TS with
lots of missing packets or bad PCRs (like the ones libavformat creates).
It still works when most other programs have given up.

Up to version 0.5.1, DVBCUT uses the "dvd" format of libavformat. The name
suggests that it is well suited for use with dvdauthor, but I don't know how
standards compliant it really is.
I tried to feed a dvbcut-generated file to dvdauthor yesterday. There
are VOBUs in it. :) But dvdauthor complains about inconsistent
timestamps a lot, mainly due to missing or bad audio frames. DVB-T
signal quality is rather poor where I live. :(
