Hi, Thanks for the suggestion. I think there's something a bit weird with dvbtune. According to it's man page the units for frequency (-f) are Hz. I am trying to tell it 11.778 GHz - but you get errors if you do -f 11778000000. Equally you also get errors if you assume it is MHz, i.e. -f 11778. Anyway, if it prints FE_HAS_SIGNAL and FE_HAS_CARRIER that must mean the frequency I gave it is OK? In any case, scan doesn't work, nor does Kaffeine, so I don't think it's that my use of dvbtune is wrong. Anyone got any other suggestions on what I can do to get this to lock?
