Actually, avidemux2 can edit the PVR's MPEG2 files quickly, without 
reencoding.

But a commandline tool, that processes the cutlist and is being called 
by Myth, would be much better. Just as you can do it within Myth with 
MPEG4 recordings AFAIK. I thought this is also possible with MPEG2, but 
somehow broken in 0.14.
