I have 3 Tivo Premieres using MRV. The feature has worked fine until recently I am having issue with one particular unit. The MRV begins to work and then about 10 minutes in I get a V87 error and suggests an issue with the network or the Tivo losing power. However, I don't think the Tivo is losing power because I it would take several minutes to reboot and I can go almost immediately go back to MRV the same show after a minute. Any idea on how I can troubleshoot this?
