Not true. It is available to subs of TWC and Directv, whom fall into the Buffalo, Rochester, and Upstate NY DMAs. I was forced to switch to TWC after six years with E*, inorder to get MSG-B HD (Buffalo Sabres) and YES-HD. I also receive the regular MSG and MSG+ in HD. Unfortunately I doubt Dish will ever carry any of them.
In retrospect, it is a tradeoff. TWC does not offer NFL Network or the NFL Redzone Channel, plus their DVR is a Chevy when comparing it to the Cadillac of Dishnetwork's. TWC's VOD and their startover feature are great though. It ends up being a matter of wants. I have chosen to have 8 months of my Hockey Team, and my Baseball Team in HD, over 16 weeks of the Redzone Channel. I will just have to suffer and watch the CBS, FOX, NBC and ESPN coverage of the NFL. BTW, I will get to see every Buffafo Bills game in HD anyways.
What it is that MSG-HD is NOT available to any one on Center ICE the problem is that the owners of MSG are in a pissing match with the NHL all this mess has NOTHING to do with either Dish,Direct,or cable.
You can only get MSG-HD if you live in the DMA which is home for MSG-HD
