I would think inactive is a correct status. If the card is not tuned to a channel I think inactive is the appropriate status.
Did you try to manually add a frequency and check if you can get the card to tune?
Also ... why do you use an analog card? Is there no option to switch to digital in your location? Tvheadend is much better suited for digital TV reception and the quality of digital TV is also better compared with analog that get's converted to digital.
