Thanks - this sounds like the answer I need.  From what I can tell, any 
device can be pushed to or pulled from, yes.  It would be nice to use 
the TVs interface though.  Outside this, there will be no OSD for the 
interface, so it would be pretty useless if one has to switch between 
one input for the video display of the myth box to the other input for 
the HD transport stream just to get the file playing.
I'll see what I can dig up on this, and let y'all know.
