I have three s2 units that I regularly move programs around to and from. Yesterday, one of my units did not show up on the other lists. When I went to the unit in question, the now playing list shows the names of old DVR's that are no longer on my network, or have been renamed at least 3 months ago. I did a clear and delete everything, reconnected, and I Get the same thing. I noticed that I just got the Fall update and I suspect it has something to do with it. Please help!
