We have a Roamio Pro and 4 Minis although only 3 are hooked up and live. We also have 2 Premiere XLs. I have nothing hooked via MoCa, all hooked via cat6 cables. The Roamio Pro and minis are all on 1 L2 managed gigabit switch (DLINK DGS 3200 series). For some reason when watching live tv or recordings on the minis we are getting stuttering on most channels, especially HD channels. When switching to a channel or recording, the channel will tune in fine for a few seconds but then after a bit it will start stuttering. The connection will not get lost, it just keeps stuttering along with audio and video cutting/jumping. This happens on all of the minis. I have no problems with streaming recordings to/from the Premieres and Roamio Pro, just the minis. And the Premieres-to-Roamio Pro go through 1 more switch (and not the same one so Premiere-Premiere is 3 switches) than just the 1 L2 switch.
Looking at bandwidth and speed checks and everything looks fine, not even close to straining the network. Actually everything is super fast. I have checked all involved ports and they auto-negotiate fine, everything looks good in switch UI. Is there some way the managed switch may be truncating or screwing up the packets sent for the mini stream? I have turned off every managed feature on the switch to make it totally "passive" and the minis still have stuttered feed. I can't believe the enterprise-level gigabit switch is somehow too slow for the stream. I even wonder if there is some kind of buffering issue causing mis-timing or something because it's only the Minis and not the other TiVo boxes.
Been troubleshooting the settings of this switch as well as others in my network for a bit now and one other thing I am wondering if anyone knows, do the Tivo Minis communicate with the Roamio directly for streaming from the Roamio Pro? Or do they pass all traffic through the main network router? I am not a networking expert more of a hobbyist so I am not sure but I assume they would transmit directly through the switch to the other device but maybe there is some internet involved going back to TiVo?
I have been trying to hook up non-green/managed switch because with a green switch (DGS1024D) hooked up to the Roamio Pro+Minis the live tv would drop totally once in while (i.e. when someone went to bed and turned on that tv/mini after it had not been on all day would have to power cycle switch-which is in the basement-to get it back). If I hook the TiVos back into the "dumb" switch, it works fine with no stuttering on Minis, until the next batch of inactivity.
I am tempted to just go MoCa on the Roamio Pro and see if that works but I really want to figure out why the managed switch ethernet method is not working.
