Not really? They can be on both Direct and Dish. Phoenix TV, CCTV-4 is currently on Direct TV and Dish Network except Dish does not have ATV and Dish charges more for Phoenix and CCTV-4. $25 vs $15.99/$19.99 with TVB Mandarin. Adding JadeWorld on Dish will increase the choices.
CCTV and Phoenix are NOT part of Jadeworld though DirecTV might market them that way.
As I and other posters have already mentioned, DirecTV has an exlusive satellite carriage contract with Jadeworld to carry those Jadeworld channels and some cable systems carry a separate Jadeworld service.
There are all of the CCTVs, Phoenix, and nearly every province's main television channel on the DISH Network Great Wall package among many other options like ETTV.
