I posted about this a couple of years ago, and nothing has changed, except that I do find that regular CNN - not Headline News is usually on the channel lineup.
It really is amazing that they "won't" upgrade the channel line-up. I will not accept that they can't change it.
I believe it is designed to encourage more movie purchases.
For me, it is bad enough to be on the road. The least they could do is offer a serious lineup of cable choices. It does affect my choice of hotels.
