Just thought I would share my experience. My existing setup was: 1 HR21 dvr 1 HR22 dvr an old RCA sd receiver an old Samsung Series 2 sd dvr When I checked on-line regarding MRV it said I was eligible for free receiver upgrades. I confirmed this with the CSR when I placed the order, everything not compatible would be upgraded for free so that MRV could work (I had to pay the $99 + 49 install fee) ... So when the installer arrived he said no, the CSR was wrong. Everything would be upgraded so that I could use SWiM & DECA which would allow for MRV between the existing HD boxed but I would need HD receivers at the other locations. I knew this but assumed that my free receiver upgrade for MRV would naturally be HD receivers since that was what I was upgrading to. He had a free SD dvr and SD receiver that were SWiM compatible but said I needed to call DirecTV in order to get the HD ones required for MRV to work. So I called DirecTV and complained that my whole house MRV upgrade wasn't really that since I could only MRV at my existing DVR's. They said that I would need to purchase HD receivers (at $99 per receiver) for this to work and when I pushed back and said I should have been informed of that when I placed the upgrade order as I may have decided against the upgrade had I know the free receivers wouldn't get me whole house MRV and I would need to purchase HD receivers. He said he would check and sure enough I was eligible for 1 free HD receiver upgrade. I said I really need two, he checked and I could only get one. He did say that if I signed up for the premium channels at a reduced rate ($21) I could get another HD receiver for free. He said that I could cancel after 30 days and there would be no penalty so that's what I did. Just wanted to let people know to make sure you know what you're getting when you get your free upgrade receivers.
