Cutting mpeg movie files (mpgtx)

I recorded a documentary from TV as mpeg2. To be able to distribute it via the internet I need to shrink its size and I am using the DivX codec. But first I wanted to trim the beginning and the end. I used mpgtx, a very handy command line tool. There are Suse RPMs from Packman. The command was mpgtx -s tutkittu_juttu.mpg [00:22.50-26:55.00] -o cut.mpg
