I have an issue with pausing, circle spinning around, and stuttering/lagging on my Sony TV with built in Android TV. Once it starts on a show it's almost impossible to get it to stop. At the time it starts, I'm usually fast forwarding, and the show was recorded very recently.
I don't seem to have the issue on my two Nvidia shields. One is wired 1 Gb and one is wireless.
The Sony TV is wired (have also tried wireless).
Server is on an older windows 10, 6 core amd 8 GB of memory. Dvr drive is a WD Red 4Tb 5400 drive.
Speed test from the DVR server to my Sony TV Android TV (100Gb connection) says download 100.02, latency 7.82, Jitter 2.14.
