Roamio Plus Bandwidth Limitations?

I setup a Roamio Plus and 3 Minis a few days ago and noticed some stuttering video on two of the Minis while transferring shows from a Permier. Was wondering if what I was experiencing was a bandwidth or processing power limitation of the Roamio? Here is my setup:



- Verizon Fios service. Coax connects from ONT to the house's coax network (hooks up to the input of a 4-way splitter). Cat5 from ONT to Linksys AC1900 router. MI424WR Rev I router reconfigured (DHCP disabled, etc) to simply create a Moca network and is on the same subnet as the Linksys. Coax from splitter to the Fios router. Cat5 from Fios router LAN to Linksys LAN.

- One Roamio Pus and three Minis, all connected over Moca and utilize the MI424WR's moca network (Roamio is not creating its own Moca network). The Roamio and Minis are the only devices on the Moca network

- Roamio and Minis all report Tx/Rx rates from 240 to 260 from the Tivo network status menu

- Basic Premiere model that is being replaced is also temporarily connected to the Linksys LAN over cat5 in order to transfer 30 hours or so of HD programming to the Roamio.

- All splitters in the house are new and from Verizon with a frequency rating of 5-1675mhz



While transferring the tv shows from the Premiere to the Roamio, I noticed that I could not have more than two of the Minis streaming live tv and not have stuttering video (Roamio was also playing back live tv). If I started live tv streaming on the third Mini, that Mini and one of the existing Minis that was already streaming would start with stuttering video after about 2-4 minutes of streaming. If I stopped streaming live tv on one of the Minis, the stuttering would also stop and live tv would stream smoothly on the other two Minis. This was not limited to a specific channel and rebooting the Minis did not solve the issue. If I chose to stream Netflix, for example, on the third Mini (instead of live tv), the other two Minis would not experience the stuttering video. Again, only live tv simultaneously streaming on all 3 Minis would produce the stuttering (while shows were transferring from the Premiere).



So basically, no more than two Minis could stream live tv smoothly while shows were transferring to the Roamio. Once all the shows had been transferred, then I could stream live tv to all of the Minis simultaneously without any stuttering. Does this sound like normal behavior, a network bandwidth issue, or a Roamio bandwidth/processing power issue?



I also had a weird experience with the Roamio that after several hours after the shows had transferred and was watching live tv, the Roamio all of a sudden rebooted and went into a reboot loop. The only way I could get it out of the loop was to disconnect the coax, let it boot up, settle down, then reconnect the coax. Everything seems to be working fine now but was wondering if this was something that I should be concerned with?
