I was moving one joey to see if the remote could be picked up and took the coax off to extend it. But the picture remained. It did not freeze. I could change channels, go to sysinfo and it showed a good link. Well, I know it ended and froze the picture on the other joey, but it did not have a network cable in it. Going back to the mysterious joey, I see I have a cat5 cable plugged into my network as is the hopper. Disconnect, and picture freezes. Conclusion: The joey can link to the hopper over CAT5E or CAT6 OR MOCA on RG6! I have tons of CAT5E and not much Coax, so I can make my move test easily.
