It can't necessarily detect if the cable box is on. Does your cable box
have descrete codes for turning on and off or just a toggle code. If
descrete, you could just send the power on command as part of your
channel changing script.

Yes, this can be done. One caveat, if you are using DataDirect you will
probably need to create two lineups. One for the analog channels and
one for the digital channels. You may need to use different zipcodes
(just use the next closest zip code to you) in order to create two cable
