I have MRV and installed the new cinema device. The DVR recognized it, and I set about setting it up. That's where the fun starts. Sporadically, the DVR will forget that thing even exists, and then it will completely disable MRV so that I have to reboot all of the receivers. I finally took the stupid wireless adapter out of the rotation so that MRV would work, but we really would like the on demand to work. Any thoughts?
