[mythtv-users] Live TV with multiple tuners

[Justin]

When changing channels in large tv using channel up and channel down it 
will only cycle through channels that exist on the current tuner.  Is 
there a way to make it cycle through channels that exist on all tuners?  
This is an issue when I have multiple sources with different channels 
and i'd like to be able to surf on live tv and see what is on without 
worrying about which tuner i'm on. 

Thanks
