[mythtv-users] switch Picture-in-picture via the B Key

[Markus Amann]

Hi
nothing happens when pressing the B or the N Key .
like it is described in the Docu
--------snip--------
If you have two or more tuner cards:
- V toggle Picture-in-picture on or off
- B toggles the window focus (lets you change channels on the PiP window).
- N swaps the two channels by changing channels on both cards.
--snip----------
do i need to add more tv channels for the second TV Card to switch the TV 
-Channels ?
I think it uses the same Database.
some Ideas maybe a bug ?

cheers
