[mythtv-users] Need help to understand DVB-T problem......

thanks for all your answers......

I've read somewhere that scanning channels inside of myth is no good,  
and the better way would be to import a channels.conf.....this was a  
big mistake.

after deleting all capturecards, and related settings, I used the  
builtin channel scanner function of myth and et voila, all channels  
appear.


thanks
thor
