Steps to reproduce:
- Start Emby Theater
- Click on Live TV
- Click on...
- Program under "Now Playing" and it works fine.
- Guide -> the title of the program that is on now -> Play and it shows loading animation but doesn't playback the program.
Server log attached. I tried the latter at about 3:37 and 3:40, maybe 3:42 too. Then I tried the Former two times after that. Every subsequent test was the latter.
