I have the same stick. You know it has two aerial inputs, yes? You need 
to define two cards in mythtv-setup and you'll need an aerial plugged 
into both inputs. As far as I know, it is random which input is which, 
if you see what I mean, so you can't really test this device properly 
with only one aerial plugged in, or with only one capture card defined.

Cheers,

John
