Hello,
It seems to be similar with: [BUG][DVR]Channels with "Unknown Airing" are not played
OS: Debian 10.2 amd64
Plex server: plexmediaserver_1.18.3.2156-349e9837e_amd64
Browing TV Guide, some channels displays “unknow broadcast” (diffusion inconnue in french) and there is an error playing this kind of channel.
These channels are working fine using VLC.
