Problem with multiple transfers

I have two Tivos -- a new Roamio and a Premiere. My setup until this week was the Premiere and a Tivo HD. I often transfer tv between between the Tivos. Starting the first transfer is working fine. When I add another transfer, what used to happen was I'd get a screen saying that the new transfer would be copies after the transfer in progress was done. OK fine. With my new Roamio and Premiere combo, however, I don't see that screen. I just get the blue spinning wheel until the request seems to time out. No screen about adding it to the files to be transferred, no sign of it in history or to do. The same thing happens whether trying to transfer from Roamio to Premiere or vice versa. The Roamio is connected via Ethernet to the router. The Premiere is connected via Ethernet to a Powerline adapter in the bedroom.



Any ideas on how to resolve this? The Roamio is the new factor here, but shouldn't it be able to add more than a single transfer?
