Is it possible to have multiple EPGs? I have both DirecTV and Comcast Digital Cable.

Also, how do I get my EPG to be configured so that it changes the channel. I hit the buttons but it doesn't do anything...

Canthe EPG control multiple EPGs? I have a Sony HD receiver in the theatre and an RCA DTC100 HD receiver in the family room with the plasma....

Brand new here and learning by Trial and Error...

Thank you all in advance...
