Just tried Unraid DVB, installed LibraELEC 6.7.0 and Unraid 6.7.0, and rebooted.
However when rebooted, it does not seems like it's installed?
Update ! Figured it out. Turned out that I missunderstod how you could install driver + OS.
I thought I had to chose ect 6.7.0 driver and same OS. Turned out I only installed new OS this way each time, and never the drivers
