I see where you're going with this, but I want to play the files, and never have to manually convert them. The point is that my Nexus 7 should just be another way to watch recorded TV. I shouldn't need to pick the shows I want.

I'll look into automating the conversion. A scheduled job should do the trick, provided I can get the converter to run with no interaction. And most of the ones I've found have got UI (and it's usually hideous).
