After re-reading your reply I perhaps ought to clarify.  At present it's 
a one-recording-at-a-time, console-based script.  I think the procedures 
in it could probably be adapted as a drop-in replacement for 
mythtranscode for some kinds of recording (and user requirements), but I 
don't have a version like that.
