Looks like your computer is suffering from PMT :P

mythstef, why would a Knoppmyth machine be looking in /recordings/livetv ?

It looks a lot like you have changed the path for tv recordings, so your tuner is looking for a non-existent directory.

You can either:
1. Go into mythtv-setup (alt+2, alt+s), correct this, exit out of mythtv-setup and re-start the backend (alt+2) or
2. Create the directory structure /recordings/livetv and change ownership to user mythtv with:
Code:
su -c "mkdir -p /recordings/livetv && chown -R mythtv:mythtv /recordings" root


and enter the root password when prompted.

If it still doesn't work after you do this, post the next error message/s.

Regards

Mike
