Ever since DirecTV proactively fixed the "transmission glitch" (which I didn't know there was one till I got an email the next morning) on my HR22 receiver the other day, several of my HD channels (History HD and channels in that range) go randomly black. No 771 type messages, just black. The H20 upstairs doesn't have the problem.
