[mythtv] MPEG2->MPEG2 commercial cut code in CVS

[Geoffrey Hausheer]

Okay, I finally got the MPEG2 transcoding code integrated enough that it
works ok with mythbackend.  I changed the commercial cutting to mark
broken frames (rather than removing the bogus 'B' frames).  I don't know
if that'll help compatibility or not, but it seems to work slightly
better for me.  Since it certainly needs a bit more testing, I haven't
integrated it into mythfrontend yet.  To enable mpeg2 transcoding, you
need to execute something like this mysql command:
update recordingprofiles set videocodec = "MPEG-2" where name = "MPEG2";

This also includes the ability to rebuild the recordedmarkup table (use
the '-b' switch to mythtranscode to do it manually)

Let me know if you try it (whether it works or not)

The latest CVS includes all of my latest updates, so no additional
patches should be needed.
