Running the latest ETV version with Plex on a Windows machine. Had no trouble setting my first channel up and channel preview is working. Plex autodetected ETV when setting up the tuner, the channel shows up in my Live TV section on Plex and the guide is all correct. But when I go to watch the channel, the wheel spins for about five seconds and then I get an error. Sometimes it's S1002, sometimes it's 4294967283, other times it's a generic playback error.
