Introducing PrismCast: Browser-based Live TV Capture for Channels DVR and Plex

Playground Hacks

#1470

My Local Fox channel is no longer working. All the other Fox One channels work.
PrismCast keeps opening my Local Fox (at Fox One) in the Chrome tab, closing it, reopening it, repeat.
I restarted the service.
I disabled and re-enabled the channel.
Here's the log entries
