I recently had my house's DTV wiring upgraded to the SWM system so I could activate MRV. My system consists of two HR24 receivers and one HR22 receiver. When I called DTV customer service to activate MRV I was told that it couldn't be done until I added an HD non-DVR receiver to my system, or until I replaced one of the three DVRs with a non-DVR receiver. Is this an actual requirement for MRV? I would hate to swap a DVR unit for a non-DVR unit if I don't have to. In addition, the receiver swap will cause an additional two year commitment that I'd rather avoid if possible. I've been a DTV customer for nearly a decade and have no plans to quit their service, however with the economy the way it is, I'd rather not be committed to something unless absolutely necessary. Thank you for any information you can provide regarding the receiver requirements for MRV.
