[mythtv-users] RE:Burning to DVD (saving MPEG clips)

[myth-lane at dowobeha.net]

I also record with a PVR-250, and would like to edit and archive my recordings.
I know this question has come up before, but I haven't been able to find a
definitive answer. 

Is any software available that lets you edit out commercials and then resave
the
MPEG2 file, without requiring exporting separate audio and video files and then
re-multiplexing them? 

I know that the nature of MPEG makes this non-trivial. But is there any way of
doing it? I'd rather not have to have my machine spend long periods of time
re-encoding or re-multiplexing a file when all I want to do is cut portions of
the movie.

The other motivation behind this question is for home video conversion. I will
be transfering a lot of home movies (currently on VHS) to my machine via the
250 with the goal of burning them to DVD. I'd like to break the home movies
into chapters. So again, it would be nice to be able to record a whole tape,
open the file, select a segment, then save that segment as its own MPEG2 file.
Again, it seems like this should not take a significant amount of processing
time.

Does anyone know if it is possible to do what I'm asking using currently
available tools?

Cheers,
Lane Schwartz
