The ivtv-0.8.0 driver uses PCI IDs to detect which unit is the first
(and so has radio) and which is second (has no radio). Unfortunately
PCI ID detection for these cards seems to be particularly unreliable.
In the head of the ivtv-0.8 branch I changed the card detection so that
I no longer have to rely on PCI IDs (for Hauppauge cards only, other
cards still can only rely on PCI IDs). So it should be fixed there.
I'd appreciate it if you could check that that version works for you.
