Is the MRV available on the HR22? I downloaded last night's CE release 0x2df on all four of my HR22s. I unlocked the Miscellaneous Options menu and turned Multi-room DVR to ON on each unit. I also ensured that each unit is still connected to my network by pinging each device. However, when I press the "list" button, I can only see the shows recorded on that DVR. Am I missing something?
