We are currently using a Hauppauge ImpactVCB card for display & capture in our next generation Pencil Tester. Using the 6.4 bttv drivers for Linux, I'm seeing 4-5 black pixels at either end of the scanline on both a displayed and captured image. The desire is to display and capture a 640x480 image. It appears that image scaling is off since we do get 640 pixels horizontally, yet it looks as if it encompasses some of the blanking interval. I tried the card in an NT box with the Hauppauge supplied drivers for NT and there are no extra black pixels on capture. I emphasize the "capture" portion as I don't believe this to be a graphics card issue which I know has caused some headaches for others. The question then is, has this been observed before? Is there a fix? Are there any utilities available that would allow us to poke at the registers on the Conexant chip? The guys at Hauppauge haven't played with Linux enough to help out. Any offerings would be greatly appreciated. Rick Rubio Dreamworks SKG
