I just received a refurbed H21 from Directv. Now I'm thinking I should return it before I activate and get an R-22 from Solid Signal. I do already have HD, DVR, and unsupported MRV services. No SWM. This receiver (H21 or R22) will be replacing an R16. Couple things I'm not sure of... 1. Does the R22 play well with the unsupported MRV? (Can't imagine why it wouldn't, just not sure) 2. Does the R22 support 1080p? 3. Anyone one have a suggestion/reason to keep the H21 over getting an R22? 4. I assume the R22 does not require SWM. Thanks for any help/advice.
