Thank you Martin, this is a nice description!

When recording from TV, I usually cut out commercials from the stream
with dvbcut (which is not only for MPEG-TS, in spite of its name). I
haven't had good luck with GOPchop (it crashed all the time),
additionally, dvbcut has individual frame precision. If the cut does not
happen to be on an I frame, dvbcut recreates all the previous frames
needed to make the first frame an I frame.

A side question, maybe someone knows the answer (Hans?): why do the
captures (Hauppauge PVR-150, stream type DVD) contain often PTS jumping
back in time? Could this be in relation to an NTP daemon running in the
background and adjusting periodically the hardware clock? I admittently
don't know exactly how the PTS are calculated and what is their relation
to the hw clock.
