Far too long a story and far too much swearing but I finally got 10.0.1 installed.
And immediately the TV function stopped working. I've got TVheadend installed as the front & back ends, they worked perfectly before on 9.2.6.
I've also tried MythTV and NextPVR for front ends but both refuse to work as well. The only thing that happens is a message up the top-right of the screen
"PVR manager is starting up 0%" and a circle that spins around and that's it.
It's a generic PC-based box.
Any suggestions please?
