I have tried  DVBcut - but unfortunately, it does not recognise my 
videos (although I can play them with mplayer - and mencoder has worked 
in the past as well). When attempting to open the file, I get "Unknown 
file type".

midentify tells me e.g.

This is what I had tried in the past running Fedora - currently, I am 
using Ubuntu 11.10 .
