[newbie] Hauppauge, BTTV, BT848, WinTV, KWintv... Any Experts out there?

[Sevatio Octavio]

I'm hoping one of you guys/gals have had experience with the Hauppaugh WinTV PCI card. 
 I just can't figure out why my tuner won't
change channels.  I get snow and that's it.  KwinTV, BTTV & BT848 software and drivers 
were installed.  Any insights or suggestions?
