I have 2 Hubs on my network and they play content from my server. One Hub is plugged in to a Gigabit switch where the server is also plugged in. The other one is in a bedroom and it’s plugged in using a Gigabit powerline adapter and this adapter is plugged in to my main router/gateway.
The Hub on the gigabit switch plays all my movies without a problem but the one on the powerline adapter has problems playing 1080p videos. The videos are rips from my Blu-ray collection like Avatar, Captain America and Star Wars. They are all about 40-50GB each (just removed a few subtitles and tracks) and either mkv or m2ts.
Basically, the movie starts fine and then after 30 secs or so it starts to stutter and video playback is really choppy. I’ve tried turning media library off and sharing as well but nothing helps. BTW, the powerline adapter seems fine as I can get 10Mbps+ download speed on speedtest.
