I have searched for an answer here and not found it exactly, so I apologize if this has been addressed. I have had 4 visits from tech's that have no idea what is going on. I continue to drop the ability for my 2 DVR's to be seen by each other and my other HD receivers. My last visit they even swapped out one of my DVR's as they thought that was the problem. If I reset every box, the sharing comes back for a little while and then I will get a message on each TV that it has lost connection to the DVR's. If I turn sharing off the receivers can then see the 2 DVR's, but when sharing is on, they cannot be seen. My equipment is: 2 H24-100 1 H21-200 1 HR20-100 1 HR21-700 (this is the one they swapped out on Wednesday) I have a phone number with a Pin to call customer service to get this taken care of, but I have a feeling they won't know either. I also read some things about VOD, and both DVR's have the Deca plugged into the top ethernet port, and I have the bottom ethernet port plugged into a wireless bridge on both for sharing media, streaming and VOD. Everyone that has come out has not seen this as a problem, but I don't know? Any help would be appreciated. Thanks!
