I currently have an HR-20 & R-16. Directv will be here Tuesday to install an additional HD-DVR in the basement. The HR-20 is already networked, and the new DVR will be connected to the same network. Will they still activate MRV? I saw in the unsupported thread some were having problems getting it re-activated, etc. Anyone had luck with it? I'm already getting the HD-DVR, and installation free, and they didn't seem too willing to go free on the MRV equipment.
