I know I _have_ done this with ffmpeg, but as you have probably found 
the man page is a pain.  I use avidemux for simple clipping.  A good gui 
for finding the right spots to cut and can recode basically any way you 
want.  (A bit of a pain to figure out the first time, but you can save 
your defaults)  If you need a CLI solution, post back and I will see if 
I can find my notes.
