Various Movie and TV Playback Issues Resolved

Well after giving my system a thorough testing, I was a Little hasty to say all the issues are resolved.
Actually no issue has been resolved. The files I tested were mp4, I was mistaken and thought they were mpeg-ts.
I still have searching and encoding issues with “MPEG-TS” encoded TV vids. Also with the H265 (x265)-MKV movie vids, I still must force them to direct play.
Still I believe this is a result of ROKU updates. I may have to start pulling tv vids as MP4 instead of as TS.
Sigh…

So the below message did not actually resolve anything.

Within the past week I noticed a few strange issues when viewing either movies or TV through plex.
Suddenly every movie I watched was being encoded for local playback. I just Forced Direct playback and did not think anything more about it.
Then I noticed a playback issue when playing tv files, I was unable to seek either forward or backward. I tried changing some settings within plex but nothing helped. Tried rebooting plex server and ROKU, no resolution. All in all, a lot of playback issues were becoming a pain in the pa-toot.
Today I checked another ROKU box within my network and had no playback issues using that device. I knew then it was not a PLEX issue but a ROKU issue. Both devices were the same Model, 4200x Roku 3. Software was not exactly the same. On the device which was exhibiting strange playback issues, the software was 7.6.0 Build 4125. On the device which was playing fine with no issues, the software was also 7.6.0, but the build was 4125-04. I attempted but was unable to force an update to the “4125-04”, So I did a factory reset on the Roku device. After setting everything up the device automatically updated to the 4125-04 build. All of the playback issues were resolved with the latest ROKU update .

I was quick to believe this was a Plex Issue… When in fact turned out to be a ROKU issue…

Also I am running an Un-raid (ver 6.3.4) box, on an Asus Z97 i7-5775C 3.30GHz. Encoding movies to H265 (x265)Codec, MKV Container, with chapter markers and Subtitles with No Default No Burn and No Forced, Using VidCoder. For TV I am pulling from various sources and usually getting MPEG-TS container files.
