Just make sure you don't go playing with her erroneous zones
Is that desired behavior, or do we want to file a bug to revert it? Personally, I agree with Ray, F7&F8 should be next and prev chapter. Channels should be Pg up and Pg down.
The other thing that I am curious about is do we want to differentiate between live and recorded TV in the remote configuration? Having channel buttons while watching a recording is pointless as they do not do anything. It might be nice to be able to re-purpose those buttons for other functionality.
