I will try a complete router refresh (IP addresses & reset) and then re-run network information.
I'm not having any other network issues. Even the DVR that isn't working is actually connected to the Internet, gets VOD, Pandora and I was able to set a remote recording online.
I did reset the bridge and I was happy that that DVR continued to operate and see the other.
Again, thank you to everyone for suggestions. I will let you know how it turns out with the router refresh.
So clearly, the bedroom DVR is able to open a session with Pandora's servers, DirecTV's servers and the other DVR. However, the other DVR can not open a session with the Bedroom DVR.
I am not sure how DVRs register with each other for MRV - i.e., do the DVRs send an advertisement packet to announce themselves, or does each DVR poll the network and wait for the others to respond.
In any event, it would appear that either the bedroom DVR's advertisement, or the poll/response session, is not getting through the bridge.
What is the make and model of the bridge? Does it have any configuration options regarding bridge mode? Does it have any security features?
