I just got my Roamio Pro set up last night. Everything seems to be working fine, except I cannot transfer shows between my old Series 3 boxes and the new Roamio Pro. I can transfer shows between the old Series 3 boxes still.
From all three boxes, I am able to see the other two boxes at the bottom of the Now Playing list.
From the Series 3 box, if I try to select the Roamio, I get a message saying "The <Roamio box name> DVR has no recordings. Press LEFT to return to the Now Playing List." There are, of course, in fact recordings on the Roamio.
From the Roamio, if I try to select either Series 3 box, I get a message saying "The <Series 3 name> DVR's My Shows cannot be displayed because of a network problem. Press LEFT to return to the My Shows List."
From either Series 3 box, if I select the other Series 3 box, I am able to see the list of shows on that box and transfer them without problem.
All three boxes are on the same subnet (255.255.255.0). All three have IPs in the 192.168.1.x range. All are hardwired with ethernet to a gigabit switch.
The Roamio Pro and one Series 3 box are plugged into the same switch. The other Series 3 is in a different room, plugged into a different switch. (These two switches are connected together.) Again, I have no problems transferring shows between the two Series 3 boxes, so the switch config is not the issue. Furthermore, I cannot transfer shows between the Roamio and the Series 3 box that are on the same switch.
I have looked at the help on the Tivo site.
Multi-Room Viewing Troubleshooting
is not much help. The first section talked about generic problems. All three boxes support MRV, all have an active Lifetime sub, all are set to allow transfers (though I will note that the setting is now called "Video Sharing"), all have a current software version higher than 9.1 (11.0k for the series 3, and 20.3.6 for the Roamio), all are on the same tivo account, all are on the same subnet, all have the same Media Access Key, and none have special characters in the name (unless a space is a special character, which all three boxes have, but it doesn't seem to hamper the two series 3's from transferring to each other). TivoToGo is a,a,a for all three boxes.
Multi-Room Advanced Help
talks about additional help for Roamios with sufficient software version, but my box doesn't seem to be doing what it says.
"From TiVo Central > Settings & Messages > Help > Whole Home View… > Streaming Between TiVo Boxes > Multi-room Advanced help"
I go to the Help menu, and I don't see a "Whole Home View..." list, just "Whole Home". Selecting it allows me to select a "Streaming Between Tivo Boxes" item, but there is no "Multi-room Advanced help" option underneath it. It just shows some of the same debugging info as related above from the TiVo web site. Selecting "Transferring between TiVo boxes" (which is what I am actually trying to do) provides some generic debugging info, none of which is relevant to my problem.
In neither case have I been able to get it to generate the "Information displayed on the Multi-Room Advanced Help menu" information, which is supposed to list all the DVRs on the network, along with their various stream and transfer diagnostics.
So, I'm at a loss. Any suggestions before I try calling TiVo?
This is important to me because the Roamio is replacing one of the two Series 3 boxes, but I still have a bunch of shows on the old box I want to watch before I sell it or give it away. Unfortunately, because of my setup, it's not very convenient for me to keep them both actually connected to the TV full time, so I was planning to just keep the Series 3 connected to the network, and just transfer the shows over (either in bulk, or as I am watching them). I'd also prefer not to transfer them to the other series 3, since it's in a bedroom where I don't do a lot of comfortable TV watching.
