Well, I'm now getting all the channels I'm supposed to get.
SCI, TLC, AMC, DIS, FAM all in HD and working properly.
I guess my only complaint, and some of you have pointed at this, is that most of the content on these "new" channels isn't great. I really don't understand the deal with SCI and TLC's use of almost-full-screen. Animal Planet does this too and it drives me nuts.
At least everything works. Now if they could just scale the content a little better...
