Hi Mick,

Are you getting radio, analogue and digital TV with this card now? I've
got digital TV, which is reasonably easy, (see
http://wiki.linuxmce.org/index.php/Leadtek_DTV2000H if you don't) but
haven't managed to get radio or analogue going.

On this topic, do you find this card seems to strugle with HD TV? or is
something in my system?

cheers

Jon
