Whatchel,
You do realize that Bell ExpressVue, and Dish are totally separate companies that sign and negotiate their own carriage agreements, Right?
Since these companies are totally separate one companies carriage agreements have nothing to do with the other.
AMC HD is not coming to Dish anytime soon. Why you ask?, Because Dish and Rainbow Media (owner of AMC HD) are in litigation for the removal of Voom from Dish's service. Until this litigation is settled no New HD channels from Rainbow Media (We HD, IFC HD, AMC HD).
