I am unable to play Live TV provided via XTeVe. However, Plex for iOS and Plex Web have not issues playing the same channel.
The Plex for Mac starts the stream after clicking the show from the guide and starts the spinner. After about 10 seconds the spinner hangs and the app becomes unresponsive.
[FIXED UPDATE]
It appears to be working now.
