I STILL have the problem as described here.
I understand the root of the problem is watching the original MPEG2VIDEO Direct Streamed/Played from the server to the CCwGTV. It’s simply unstable in the Plex app code or CCwGTV device itself. Everything I see points to the Plex app code quality.
They key is to configure the Plex app such that it always gets transcoded to H264.
I’ve attached a link to my solution for fully recorded TV content at the bottom of this post.
That solution does not work for live TV or currently recording (timeshifted) TV. The quality never bumps up to better quality with the settings as described.
For live TV I have to watch using Plex Web in a browser.
From what I read this issue seems almost completely related to the Plex app on the CCwGTV.
