It's not supposed to any more because the keymap was removed. Instead,  
you want to use Next Input instead of Next Tuner since it makes more  
sense (there may be more than 1 input on a card that you would never  
get to by cycling through tuners, but you would by cycling through

That was never the default behavior. There is an option to allow  
LiveTV to reschedule programs, but it has o be explicitly set.

That's because the "best" tuner (the one you said to use first) is now  
being used so it picks the next one in the list.

The other way to do it is to press M(enu), then choose which input you  
want to jump to. This is great if you're like me and have 6 tuners and  
know which one you want to use and it's not the next one in the list. :)
