In answer to the earlier questions the remote is standalone. Only the RF receiver and a Samsung Bluray player that I neglected to mention are the only things besides the other devices.
So scheduling is in a separate processor then? Which I don't have here so that eliminates that. I didn't see any time/date on this unit so I kinda figured it was not possible unlike the URC remote.

I watched the TV turn on while I was standing there. The Comcast box never turns off. The DVD player I can't remember if it turned on also but if it did and it is also a Samsung maybe this anynet or BDwise is the culprit.
