I have an owned 942 that was never activated and is still in the original box from Dish. I'm using a 622 on my main TV and an old (but still working great 510) on the SDTV I have in the bedroom. Assuming that I want to upgrade the bedroom tv in the next 6-12 months, I'll want a new (HD) receiver. Do you think it's possible to have Dish "upgrade" my 942 to a 622 but not have it activated until I actually plug it in? The 510 has no DVR fee and it's fine with the TV I have, but if I can get something out of the 942 now, I'd like to do that.
