Thanks for the heads-up about Blue Planet! I'll probably try to rent it as I'm not much of a TV watcher. :)

I don't know how easy Comcast digital cable is to use because I don't know how to use it. *blush* I can turn the TV off in the sense that we have three remote controls and I don't know what goes to what, so I just press OFF on all of them. If Bobby's going out and I want to watch a sports game or a program, he sets it up for me and tells me which remote I have to use to turn it on. Last time, he even showed me how to adjust the volume, and I had to say, "Okay, I'm not that stupid!" :^P

(Though two of the remotes have volume controls and it took me a while once to figure out which one I had to use, so maybe I am!)
