I just moved PMS from my computer to my Shield TV and setup the Live TV/DVR functionality. I’m able to watch live tv from both the Shield and my phone just fine. However, when I try to access Live TV from the browser it doesn’t work, it only gives me the record option. When I had PMS installed on the PC it worked fine.
PMS on Shield: Version 1.8.1.4139
Plex Web App: Version 3.14.1
Chrome: Version 61.0.3163.91
