I just purchased a Tivo Roamio Pro and Tivo Mini to replace my old 2-room / 2-tivo setup. I have these connected through 2 Netgear GS108 switches: Tivo Roamio Pro <---> Netgear GS108 <---> Netgear GS108 <---> Tivo Mini This setup worked fine with the old tivos for room-to-room transfers, but with the Mini, HD content stalls out within seconds, usually with a V87 error (network too slow). This occasionally happens with non-HD content as well (live tv and recordings). I tried to measure network bandwidth by connecting 2 Macs where each of the tivos are connected, and ran the iPerf program. This consistently gave me around 940Mbps, for a variety of packet sizes (close to the 1Gbps maximum). I've also tried power cycling all the boxes, assigning static IP addresses, and even removed a switch, but nothing seems to fix the problem. Tivo technical support was not able to help either. I'd appreciate any suggestion on what to look for or how to diagnose the problem.
