Lost connection with networked RTV solved

Recently, I lost the connection between RTVs on my network. I could see the program list, but got a network error when I selected the recording. I have Buffalo routers configured as bridges on two units with a third hard wired to my Buffalo used as a router. After rebooting the RTVs with no joy, I unplugged each of the Buffalos and let them reboot. Immediate fix. I believe the problem started when we had one of many (I live in FL) brief power outages. Just something to try in case anyone has a similar problem.
