Thanks for the info.
I guess I knew that since I have one for my upstairs HD tv. But, yes, I was surprised it was an option when I went into the office to get one.
BTW - I believe it's the interaction (business negotiations) b/n Comcast and Samsung that delayed getting HBOGO - so not all Comcast's fault. I am having trouble with Samsung now getting them to put the Amazon Instant Video app on my 2011 Samsung - the only year they chose not to have it. (As if I don't have a million viewing options already!)
