[mythtv] Detecting stream types

[J. Donavan Stanley]

I'm finally ready to start working on DVD recording for Myth.  I've 
gotten the tool chain figured out (at least for x50 cards) and made a 
DVD of a movie from HBO.  If the stream is a PS or TS stream I need to 
remux it before burning it.

I apologize for asking this before digging into it myself but I've got a 
dozen things going on and I thought someone could provide a quick 
answer...  Is there an easy way to determine the stream type of a nuv so 
that I can just automaticaly remux those that need it?
