Hmm, yes, I was hoping to avoid having to reboot the system to do 
editing, but that would get around the fact of my Mandriva 2005 being a 
bit outdated, so I will probably try that.  (Eventually I'll have to 
update that.)  Part of the problem is that I'm finding the codec- 
versus-container issue rather confusing.  I mess with audio files a lot, 
and I use mostly command-line tools for that.  I'd very much like to 
made something that would simply "extract from frame X to frame Y."  So 
far the closest I've found is avisplit, which splits a video file into 
equal pieces.
Thanks for the suggestion!
