dvbcut is a Qt 3.x application that allows you to
select certain parts of an MPEG transport stream
(as received via Digital Video Broadcasting) and
save these parts into a single MPEG output file.
It follows a "keyhole surgery" approach where the
input video and audio data are mostly kept
unchanged, and only very few frames at the
beginning and/or end of the selected range are
re-encoded in order to obtain a valid MPEG file.
