Background: I am using Emby on Roku Ultra, Fire Tv (4K) and LG TV (Emby built in app).
Have copied several movies to Emby Server and they pixelate using Roku Ultra. They work fine using Fire TV (4K) and LG TV (Emby built in app).
Roku Ultra is about 1 year old and it works fine for everything else. Roku software is up to date; Emby was downloaded to Roku this week (11/20/2018)
Any ideas on how to fix this?
