Thanks for the script! I have been playing with avidemux and your script
a little bit. The bottleneck is the cpu :-(,  so the amount of 'playing' is
limited. But instead of generating '.edl' files, it might be better to use
the scripting capabilities. You can set the markers, but you cannot delete.
But that shouldn't be too difficult to implement... Another thing is that
The myth cutlist is not (neccessarely) on I-frame boundaries. The doc's
suggest that it is much better to make sure it is (although I have no
idea how bad it looks if we don't) . So that is a point to keep in mind
too... Positive thing is that Myth and avidemux seem to be agreeing on
the frame numbers. I'll see if I can manage to build avidemux from source
today...

Do you know how the running time of the mpeg can be determined? We need
to know the running time after cutting. That way the wanted size after
the encoding can be determined.
