I currently have a Roamio Plus on MOCA, a Premiere on MOCA (via an adapter), and a basic Roamio on my ethernet LAN, via 2 stitches and a RF bridge. The basic Roamio can see and play shows on the other two TiVos. KMTTG and TiVo Online Manage see and control the basic Roamio just fine. I am certain that the Premiere and Plus could see and play shows from the basic just fine until a week or two ago. BUT the Premiere and Plus cannot see play shows from the basic. If I restart the Plus or Premiere they can see the basic and show the program list but I get a network error if I try to play a show. Does anyone know if TiVo changed software to limit communication through multiple switches or a RF bridge?
