when I turn on x1 it takes quite some time to get guide or anything else. My other 2 tvs no problem. I also have surround sound on each tv. Was told by installer in order to have surround sound I would need to use 2 remotes. Is this so or is there a way to program my receivers in to use only one remote. Also should th round green light be on even when all off is pushed? I'm new to comcast.
