there is a lot of depends on. I know Dish network, dropped all Disney based HD channels a few months back. I don't remember the exact dispute but I understand the position of Dish.
As to full channels lots, we used to have Kung-fu channel and the related but they dropped them a few years ago. It was nice to see some of the older Kungfu movies etc, (monster etc were in the package) I was somewhat upset but I just shrugged my shoulders. I will say those channels had some really nice HD.
