No compensation required. They didn't raise the price of that channel package when they added the DVD-mailing service to it.
They didn't add DVD-mailing to any package. They discontinued the Platinum package and switched everyone who had the old package to a different new and improved package, MoviePass. This happened between the August and September 2011 bills. MoviePass was advertised as a "answer to Netflix" (http://www.theverge....treaming-videos) and included discs by mail from day 1. Discs by mail was not a freebie or a perk. It was an advertised feature of the new package.
From the Sept 8, 2011 bill:
"Attention: DISH Network is pleased to announce your DISH Platinum subscription has been upgraded to the Blockbuster Movie Pass©. In addition to the channels offered in DISH Platinum, you'll get unlimited access to thousands of movies streaming to your PC and TV (requires Broadband Internet and compatible HD DVR) plus over 100,000 Blockbuster© titles by mail -- with no change to your package price. Visit dish.com/BlockbusterMoviePass to learn more. Your tax rate may change based on your state and local tax laws."
Nobody is on Platinum anymore. They didn't add any features -- they cancelled it. The clock stopped there and started fresh at day 0 on MoviePass. I've been paying $10/month for MoviePass, a package which began with HD channels, content streaming and discs by mail. As of mid-September, that package is having fewer features than when I initially signed up for it (or rather was automatically signed up). It's probably no coincidence that the program started in one September and is getting changed in another, but I'm not sure what that means.
Looking through bills, I also see that in 2009 I switched from HD Silver to HD Platinum at no additional cost. So I suspect that Dish found a way to get an additional $10/month somehow through the transitions from HD & Platinum to HD Platinum to Dish Platinum to MoviePass, now BlockBuster@Home.. I'm fuzzy about all the details but I do remember calling Dish service at one time to complain about a charge increase and I think that's when they told me the discs by mail service was new and so I kept it. (I don't watch those movie channels much, and probably got Platinum because it was a free upgrade which I read about here).
