Myth knows what lineups are connected to what inputs.  So if you have 
your DirecTV receiver plugged into SVideo and an antenna plugged into 
the antenna part of your capture card Myth is smart enough to say 
"Channel 12 is on the tuner and I'm currently on the Svideo showing 
channel 222.  Let's switch over to the tuner before changing to channel 
12".  Works like a charm.

It gets a bit trickier if you have multiple cards and multiple inputs on 
those cards but it's manageable.
