They offer 25 HD channels, 6 are HD PPV (movies, adult, events)
10 are the US networks (CBS, ABC, NBC, Fox and PBS)east and west feeds
Two are Canadian sports channels
Three are Canadian Broadcst Networks (two channels, one is the east and west feed)
There is one movie channel kind of like a Voom21 offering (you choose one of two offereings for some reason you can't get both)
Discovery is HD but different than Discovery HD Theater here
They do have WGN and a canadian superstation in HD that is alot like TBS or TNT
But, you must pick some packages to get what you want. To get all of the HD, plus a bunch of SD (some you must have to get some of the HD channels- for instance, you have to have a movie package to get the movie HD channel, etc) it runs about $55 US per month. They do not offer any of our movie channels that I can tell (HBO< Starz, Showtime, etc.) which is a killer for most people.
When I originally posted, I was hoping to add a pack for just HD channels, but just like D*, E*, etc. you have to also get a bunch of stuff you don't want.
