I just made it properly initialize the card, it wasn't doing it completely 
before.  If you browse through the CVS tree, you can probably find the commit 
with that change in it -- I think it's in tv/channel.cpp

Currently, it just deals with the RF input.

Can't switch between em in the current codebase, no.  It really shouldn't be 
all that hard to implement it, though.  I'd be happy to give you pointers and 
eventually accept a patch that does that, if you're so inclined to work on 
one =)
