Manu,

it's a KNCOne TV-Station DVB-S
on it, I can see a STV02998 and a SAA7146AH
the tuner chip is obscured by a cover plate
I've prepared a little page with some pictures and the dmesg, lsmod and lspci info :

http://www.bsc-bvba.be/persoonlijk/kncone.html

even though I bought it as a TV-Station, and that's what it says on the box, it is taken to be a TV-Star
if I change the PCI-id-table in budget_av.c and make it a TV-Station (SUBID_DVBS_KNC1), I get "timeout waiting for end of xfer" from the SAA

the budget-av coding for the TV-Star seems to suggest the tuner is a SD1878, which is confirmed by the label on the cover plate (you can read it on
the pictures of the front of the card)

I'll go and read the SD1878 coding ...

Luc
