This may be too little too late but:

I've used GopChop from the Ubuntu repos for cutting commercials out of 
MythTV files [1]:
	gopchop - Fast, lossless cuts-only editor for MPEG2 video files

I think upstream is now unmaintained, but it's a pretty simple GUI to 
use rarely.  It can only do MPEG2 and it can only cut on "Group Of 
Pictures" boundaries, but that was perfect for my use case.  You wind 
through the video and give it start/stop pairs to tell it what to keep 
and what to chop, then save.  It maintains closed captions correctly, 
and does no transcoding or anything, so it's fast.

I run it in my script like so, where $vid is obvious and the grep 
filters cruft out of the console messages:
gopchop -v x11 $vid 2>&1 | egrep -v 'pixmap",$|gop: Permission denied$|^$'


[1] It's easier to use the MythTV "cut list" feature for this, but I 
didn't know that at the time.  A cut list for an episode will supersede 
commercial flags, so a cut list is useful a) to cut out commercials that 
were not flagged at all, b) to override incorrect commercial flagging, 
or c) to turn off commercial flagging for something that I GopChoped 
(e.g., create a cut list of 1 frame someplace you won't miss it).

Later,
JP

"Microsoft Tax" = the additional hardware & yearly fees for the add-on
software required to protect Windows from its own poorly designed and
implemented self, while the overhead incidentally flattens Moore's Law.
