you can definitely setup the tuner in myth and do a custom record but
if you go the cat /dev/video route you can always view the mpg in real
time using mplayer which is easier.  there are a lot of ways to do
this and using myth is always an option but you incur the "penalty" of
the scheduler so doing it manually is easier IMHO.
