When I scan for tvchannels MP can't find Sverige Television 2 and MTV, I have these on my TV. MP finds all the other channels.
I try to add these channels manualy.
When I set the channel to 10 and 210,25 Mhz for Sverige Television 2, I don't get any picture. Have also tested S10 and som of the K channels with no luck.

Anyone know what to do?
