But by cat-ing several mpegs together you DO end up with a single header,
IIRC it's why the cat command exists in the first place, remember that all
it does is concatenate multiples to a single. A side effect is that you
specify a single file and no output designation it just streams the file
contents to stdout so who needs a 'type' command? :)

One trick I found, which I was surprised at, was that you seem to be able to
'cat' several mpeg files together into one and a player will happily play the
entirety of the subsequent file. Weird; I mean most formats expect a single
header and some data, but mpeg seems to be able to cope just fine with lots of
header and data segments. After that, I used a video converter program to
convert from mp4 to mpg.
They apparently are different formats.
The mpg extension doesn't (I don't
THINK) designate mpg1, mpg2, mpg3, or
mpg4.
