I have two on the wiki. Neither is fully integrated for use as a user
job. I use them from a console and I perhaps have more time for doing
this than most people would want to spare. I posted them mainly to set
out the steps involved, and they may need updating for 0.24+
The older script, for dvb-t, uses Project-X and discards all but one
video and one audio stream. The other just makes keyframe-linked cuts
and passes everything. It works with dvb-t2 as well and could be ok
Project-X cleans up some errors in the recording and doesn't have to
discard subtitles; I think mythburn.py in MythArchive would yield an
example, but everything would need remuxing and I've never bothered.
