Are ati tuner cards CableCard Capable?

okay so i recentley bought a Hauppauge 1250 tuner card but was dissillusioned into thinking that i would just plug in the cable cord and be able to watch all of the channels i pay for thru comcast on my computer. Wrong... I could only watch NTSC ATSC Clear QAM and analog tv, so some really crappy programming. SO i was looking around and i found that i needed a cable card in order to watch all of my programming that i pay for through comcast. Thats right, right? and i was wondering if ny tuner cards were Cable Card ready! So i looked around and saw that some ati tuner cards were cable card ready! Is that right? here are some of what i looked at! http://shop.amd.com/US/_layouts/shop/shop-amd.aspx... i chose those because they said they were cable card capable does that eman all i have to do is install them into my computer and using my cable card from comcast put it in the card, and plug in the cable and i could watch my regular programming from comcast? If not please recommend me some cablecard tuners that could do this!
