I concatenate mpeg files regularly without a problem.  The thing is, you have 
to be certain that the files you are catting are of the same framerate, 
bitrate, etc.

This is most successful for multipart mpg files that you want to rejoin.

This also works for avi files as well.  AFAIK, the method that you described 
is only copying a mpg encoded file to a different file with an avi extension, 
it's not actually changing anything.  The same as if you had just typed - 

   mv foo.mpg foo.avi

You could probably use file to verify this.

I'm enclosing a couple of scripts that I wrote specifically for this that may 
be of some use.  Use the concat script for mpg's and the catavi for avi 
files.

HTH :-)
