Problems streaming to Rokus

[jwclack52]

I'm having problems streaming on all of my Roku devices. Most are TCL tv's w/ gigabit ethernet connex. I also have a Roku streaming stick hooked up to a Samsung MU6290 4k TV. When I try to play using either the Roku media player or the Mezzmo app (which, by the way, never successfully finds the server on my LAN - have to manually add!) I get the dreaded "retrieving" message for minutes at a time. Movies finally load and play, but only after 2-3 minutes. I also have problems w/ FF - if I do, I get another 2-3 minutes of frozen app. Interestingly, the Samsung plays these streams fine w/ no delay, either from the start or after fast forwarding.

I'm attaching a log file of my attempts to play the same movie on the Roku Mezzmo app and then on the Samsung.
