This card is now supported in the 2.6.16 kernel as card 143 and should autodetect. It has 3 RCA inputs and 1 SVideo. It should be noted that the 3rd RCA input does not work in Linux.
Note that the card ships with either an NTSC (26Mhz) or a PAL (35MHz) crystal. The driver assumes that your camera format matches the crystal. If it does not, you will get no colour and/or loss of picture lock. Fortunately the card can synthesize one frequency from the other, but has to be told to do so with the option
bttv pll=1 (for NTSC crystal ->PAL camera) bttv pll=2 (for PAL->NTSC)
This card can be purchased in America from Newegg.
