I don't know for m2v, m1v , m4v , but for mpeg that shouldn't really be a problem. If cat does not work, use tools like ds_X, replex or pvastrumento. I use ds_X regulary and don't have real problems. My material are vdr recordings, encoded mpeg's and so on, but that should not really matter. for mpeg4 avidemux or mencoder could be a solution. ds_X can demux, remux, cut and join mpeg1/2. > Splitting the DV data is not the hard part - you could generate .smil > files with the appropriate frame ranges.

It has included a livecd to make fast and easy a cluster of encoding nodes. I don't remember though if it is alive and how it was called, it may be one or two years back when i read about it.
