Ok, I have been rescanning the channels: The problem now returns after I mapped the services:
What I did:
- removed removing .hts, bin and share and then reinstalling (from a clean source).
- Then I rescanned the adapters
Now, After this, I could watch tv from various adapters from the config/tvadapters/services tab.
However, after "mapping services" the Tvheadend load goes to 100% and the problems start.
EDIT: Ok, I am not 100% sure it happens because I mapped the services, but it seems to start 'after some time', but then it stays (after restart, reboots etc).
I will try to go through the sequence again and look when it first occurs....
