Have you got 2 instances of TVH running? Since the one in lsof has different PID to the debug listed before.

Thats the case. I dont know how to get rid of this second proccess. All was well until I installed a second videocard (analog). I removed the analog card, uninstalled TVheadend and installed again, without any luck. I tryed to kill the process (pid no), but new one started again????? I did that several times, but new tvheadend turned up again with new pid no. How can I remove tvheadend completely with all folders and files?

If you're installing the debs on Ubuntu then the process is started (and monitored) by upstart, so that in the event of a crash it will auto-restart. So to stop the process you must do it properly via upstart:

sudo stop tvheadend

and to restart

sudo start tvheadend

After I stop the process with
sudo stop tvheadend
I then do tvheadend stop and get this error.:
