I was just inspired to bring this up due to a discussion in another thread: After switching to an all HD package no more than 2 weeks ago (HD Ultimate or whatever they called it at the time) my Big Ten network and Comcast Sportsnet Chicago disappeared, even though both were carried in HD. I wasn't concerned about it at the time, but now I think that I may deserve these channels since I was grandfathered in to the Turbo PlatinumHD package. Does anyone have any idea why I should or should not get these channels?
