Hauppauge-HVR-850 not working

[Rooh2os]

My casa os (docker) nextpvr setup detects my 850 and is able to scran and find channels successfully but cannot watch any. Looking for help.

Try watching a channel, then post the logs and we'll take a look.

You haven't set a live tv buffer directory that it can use.

I set it to a tmp directory and it works! How would I set it to a directory within the nextpvr folder, as the dir that it is in is not showing?

It has stopped working again

If you're running in docker, you should be mapping directories into the container to be used for recordings and the live tv buffer. ie, not just letting this stuff be created in the container itself.

ie, leave it on the default /buffer, but then map /buffer to somewhere on your host filesystem.
