Tuner does not tune to 7 channels. Manually tuning with dvbv5-zap works. All other channels work

Server Version#: Version 1.42.2.10156
Player Version#: Any Player, but I’m using 1.110.0.351-4e48eb83 on Windows 11
Tuner Make/Model: WinTV-quadHD USB
Guide/Lineup name: Local Broadcast Listings (114 channels)
Using XMLTV?:No
Channel number/Name: MOVIES on 8.7 (8.1 & 8.2 work), 8.3, 8.4, 8.5, 8.6, 8.7, 8.8, 8.12 do not.
These channels did work, but haven’t for several months. Manually tuning to the channel using dvb tools works and creates the .ts file that plays in VLC. I can tune to the rest of the channel lineup fine. The Player states: Playback Error: Could not tune channel. Please check your tuner or antenna.

I cannot encode anything on live TV/DVR since this update. Old versions seem nuked…

Are you running the latest Linux Firmware for Hauppauge Tuners from the Hauppaugge PPA?

I can record and watch all other channels just fine. It’s just a few that don’t work for me.

Hi. It was a bit of a challenge to get the right drivers installed initially. I’ve confirmed that I do have the latest drivers. Also, the fact that I can manually tune to those stations using “dvbv5-zap -I zap -c channels.conf “MOVIES” -r -p -t 100 -o movies_capture.ts” should mean the drivers are good to go. It seems like Plex itself is failing to tune to the channel/station. I get a good video .ts file using that command.

I would try a rollback to an earlier PMS server version.

Here is what is listed in my Plex Tuner Service Log:

I’m running the Hauppauge drivers.

It doesn’t look to be a Hauppauge driver.
