I just had my MRV upgrade installation and the tech said upgrading my HR20 receiver was not part of the process. He did offer to swap it next week for a brand new HR24, for $50 outside of the D* upgrade process. My concern is will this new DVR be recognized by D* on my account or will it cause problems down the road? Perhaps he knows how to get me upgraded officially with D* and is willing to help make that happen for a few bucks? Thanks for any feedback!
