No Dual tuner

[tvviewer]

Hi
i use a Raspberry pi 4 8 GB with Debian Bullseye 11 OS 64 bit (Raspberry pi OS), Hauppauge WinTV Dual-HD and NextPVR 6.1.2.230502. I have tested that NextPVR cannot show or record 2 different DVB-C Danish channels simultaneously. It seems that NextPVR also sometimes does not release the last seen channel correctly and a scheduled recording start and then another scheduled on different channel is due to start after then the second recording will just be denied and a http 500 message shows up. Can this problem be solved thanks?

On the Settings->Devices page, do you see two devices listed with channels?

Might be worth trying to recording on two channels that are on different frequencies, then post the logs so we can take a look.

There were a few changes in DVB-C for 6.1.4 but sub still needs to update the arm64/DeviceHostLinux since the wrong version was packaged. I did post the older version here https://forums.nextpvr.com/showthread.ph...#pid584033 but that would have 6.1.2 bugs

@sub - Yes i have adapter0/frontend0 (Silicon Labs Si2168) and adapter1/frontend0
Where to find the logs?

The logs are via the Settings->General screen but they won't help for this known problem

If you must send the logs send the zipped logs not snippets, you didn't include the relevant files, but in any case this is a known problem.
