@ahiyahiya I have the same problem with a WinTV-dualHD tuner. I updated to the latest Plex Media Server and still have the issue where “Scan Channels” doesn’t work and I cannot get channels to play live. I’m attaching logs here, I hope they are the right ones.
To help make sense of the logs, here are the steps I took: I installed the update, tried to watch live TV (which failed), then removed the DVR from the settings, re-added it, tried the channel scan (which failed), continued without the scan, then tried live TV again (which failed).
Edit to add, because of this issue I’m not able to debug this other live TV issue I have: Live TV constantly buffers
