I have two DTivos, zippered, wired through a router. They have been happily MRV'ing back and forth for years. Today I suddenly can no longer transfer from DTivo B to DTivo A. However, I can still transfer from DTivo A to DTivo B. From DTivo A I can see the other DTivo in the NPL. I can search through all the recordings, select one and initiate a transfer. But nothing ever transfers. It just hangs, forever, with the recording light on, doing nothing. How is it possible that I can transfer from one but not the other unit? Could this be a wiring problem? I've checked every network setting, looked through all the logs, rebooted both units, everything I can think of. I can telnet in, TWP works fine. Everything is normal except MRV stopped working in one direction. Does anyone have any ideas what might be causing this? Any help would be much appreciated. This is driving me crazy.
