Answer 1

There is a commandline utility which does just that: http://mpgtx.sourceforge.net/

mpgtx -3 movie.mpg -b mysplit

will split the movie into 3 chunks with the names mysplit-1.mpg, mysplit-2.mpg, mysplit-3.mpg

That said, I seem to have trouble with the audio when I use this - but I don't know if you'd have that problem too.

Answer 2

calculate ~time (sec) of every block & use -ss X -t X+avg_block_time for split video
