It has nothing to do with Linux TV. This is 100% a Plex issue.
When you use a modified xmltv that doesn’t report the end of a program, it no longer restarts. So it is unrelated to the contents of the stream or any drivers/codecs used to play the video or anything in the kernel. It’s simply a badly-functioning Plex feature that’s reacting wrongly to seeing the end of a program in the TV guide
Same problem on both Windows 10 and Qnap plex servers. Any update on this yet?
I figured so much based on other people’s reports of this issue. Apparently, I finally got it to work as before by rolling back the server to the previous working version (1.19.4.2902) AND refreshing the Guide… twice. Thanks.
More forums to add to this one:
Any word on a fix timeline?
Server Version#: 1.20.1.3252-a78fef9a9

Tuner Make/Model: HDHomerun HDHR5-2US
Guide/Lineup name:
Using XMLTV?: No
Channel number/Name:
You’ll also notice that compounded with this issue, managed users can only watch live tv for 4-5 mins before the feed just closes.
Seeing the same behavior here with both the web client and the Plex app for Mac. Server version 1.20.1.3252.
Would really love to see a fix, live TV is basically useless at the moment.
Seeing the same problem on a Centos platform. Very annoying…
Same Issue Please fix this annoying problem ASAP
HI Long time user of PLexTV, I have the same problem, I currently use PLex mostly for live TV, every hour I cringe… that I need to manually start the next program.
Win Version 1.20.0.1406-f47a81b7
Server 1.20.1.3252
Please help with a fix.
Will try to downgrade to an older version.
Thanks,

OK, I tried to look for the older version of the server 1.19.4.2902, could not find it, however try to update, said I was upto date, howerver on the PLex Site it is version 1.20.2.3402 of Oct 2nd. I have installed it. waiting for the next hour to see if it is fixed.
This is for version 1.20.2.3402 - https://www.plex.tv/en-ca/media-server-downloads/
P.S. can someone tell me how to find older versions of the plex server software?
Thanks,
PC
I have found this site for archived versions of the Server Software:
Maybe this can help,
The newest version 1.20.2.3402 does not fix the issue
Yup, same issue here.
@OttoKerner Any updates on your bug report or guidance on how people can roll back to avoid the problem?
As you can see above, simply downgrading does not consistently fix this issue.
I can see that the fix has been coded. But unfortunately I don’t know when it will be incorporated into a public release.
@OttoKerner thanks, hopefully it will be soon. Wife 
aggro is killing me!
@OttoKerner Can you confirm if the fix is in the beta channel? I’m willing to switch to that in the meantime.
No, the fix is not in the beta channel yet.
Same issue watching on web (safari), Apple TV, and a Fire tv. At the TV show switch point, it starts back at the time the show was turned on. Have caught myself watching the same NFL/NASCAR over after nodding off in my recliner and not seeing the restart. 
Currently, my Octopus stops streaming completely after a broadcast has been canceled due to an error or bug. Before the stream jumped at the beginning of the playback, now it breaks off completely. I know the Octopus is not officially supported, but before updating a certain version (unfortunately I don’t know which one) it worked wonderfully.
