Thanks for the the reply.
I was hoping for a way to save favorite channels in the remote, rather than the guide.
I never use the guide. The guide doesn't list all of the channels on Directv (none of the channels with a "-" in the channel number are listed in the slingplayer guide). It's more accurate to turn the receiver on (the device which is connected to the input on my slingbox) and use its guide.
So there is no way to save favorite channels in the remote?
