[Mjpeg-users] how to join m1v and mp2 files?

[Dragon_at_work <m_g...@Be...>]

How would I join multiple m1v and mp2 files in a way that would later lend 
itself to mplexing them. 

I tried cat. And it seemed to work for both types. 

But, mplex was unable to join them properly --ie the video worked, but the 
audio did not.
