Desktop Plus/Roamio Problem

I have Tivo Desktop Plus, plus a Tivo HD connected wirelessly along with a Base Roamio connected wirelessly. All are on the same network.



Tivo desktop plus shows both Tivos.



The HD DOES show my PC in the Now Playing List.



The Roamio does NOT show my PC in the Now Playing List.



I have tried rebooting everything. I have tried re-linking Desktop Plus to my account and it links just fine. I have stopped Tivo Server and restarted it.



I just can't get the Roamio to show my PC.



Any suggestions how to get my PC to show up on the Roamio??????
