Check the code it is sending. The way I saw you set this in the 6200ch 
code leads me to believe you may not have B2 in the 3rd byte but 7C 
instead. 7C is the panel command. B2 is the power command.

as you surmised it needs a guard time as the root_menu may take a while 
to process. You should also see this when using your remote (ie. it 
won't respond to the following key press if you are too quick).

George's suggestion is good about making it a switch.

I'm not sure if anyone is actually maintaining 6200ch. I haven't looked. 
But myth does have firewire code in it now for channel changing.

Based on your research, I will update sa3250cmd as well. I should 
probably change the name of this too as it in fact will be more useful 
on non-SA boxes :-o
