I just upgraded to a Premiere 4 and it came with a MoCA adapter so I thought I'd give it a go to see if transfers were faster to my other unit which is a TiVo HD which usually transfers quite slow over wired internet for hd content. I got everything set up properly and was able to transfer from the Premiere to the HD over MoCA, but the speed didn't seem any faster. If anything, I would say it was only marginally faster, but seemed more even with no random starts and stops which is very common. My main question is: Is the slow transfer speed due to the HD hardware or a bottleneck in my network? Has anyone here had experience with transfers between two HD's or between a Premiere and an HD? Is the transfer between two Premieres any faster? What I mean by "slow" is that high def content barely transfers faster than realtime. I do have a fairly complicated network with a couple of switches, but I don't notice any speed issues except when transferring hd shows from TiVo to TiVo.
