Here is my set up.
HDHomerun Extend, a dell inspiron running PLEX, several Roku's throughout my house. The transcoding on PLEX is set to Highest quality for the Extend.
I purchased the HDHomerun Extend because the description said that the hardware inside the Extend would take the burden of the transcoding. When I try running 2 live TV streams the CPU on my computer goes to 100% and I cannot watch either on my rokus as they are constantly buffering. I tried moving the transcoding to original format in the settings, but then ROKU said it could not display anything.
Please let me know how I can pass on most of the processing to the EXTEND.
