Right.  G is the default binding for "Recording picture adjustments for 
this recorder" (TOGGLERECCONTROLS).  And Ctrl+G is the default binding 
for "Recording picture adjustments for this channel" (TOGGLECHANCONTROLS).

That (F) is the default binding for "Playback picture adjustments" 
(TOGGLEPICCONTROLS).  You seem to either a) have something else bound to 
it or b) have a card that doesn't support Xv picture controls (i.e. 
NVIDIA 6x00 or higher).

Use MythControls to check your bindings.
