[mythtv-users] Livetv -Mythtv is already using all available inputs for recording?

[Bemer]

Hi

When I start mythfrontend and watch live tv I get the following error (reboot doesn't help):

"Mythtv is already using all available inputs for recording. If you
want to watch an in-progress recording, select one from the playback
menu. If you want to watch live tv, cancel one of your in-progress
recordings from the delete menu."

Live tv has been working fine until this week....
I've searched the list and found some suggestions but nothing that works for me

Useful information:
-Nothing is being recorded and never has been
-Running mythsetup doesn't show anything strange everything is there
-Dmesg shows everything as normal
-I've tried to delete the nfslockfile.lock
-No errors are displayed in mythbackend.log or the mythfrontend (console window)
-In information center=>system status it only says tuner 1 is not available.
-I tried mplayer://SVT1 while both backend and frontend is running and yes I get a picture.

I'm using one technotrend dvb-t premium card in gentoo.
So my conclusion is that mythtv has a lockfile somewhere else or something is wrong in the database 
(some filed indicating recording is on-going but it isn't). But I dont know where to look, any suggestions?

Some additional info:
