I have now been contacted several times by Dish, phone calls and letters, saying I need to upgrade my standard definition receivers to HD by the end of the year. When I asked why, i was told that in 2012 they will stop broadcasting channels in Standard Definition and that my receivers would be obsolete. The upgrade would be free for me, and they would set me up with multi-room DVR. The new receivers would still support standard def TVs. Last year I was also contacted about upgrading to a DVR in general, and ended up purchasing a multiroom DVR. Since this unit is purchased, it wil not be upgraded as part of this offer. Any insight into this?
