I am returning mine; I get better results with my Hauppauge 1212 HD-PVR even though it only record at 13.5Mbps as opposed to the Colossus 20Mbps. I got ghosting/combing/moving horizontal-bar-noise with my Colossus and tried using the high-quality component cables I retrofitted to my "1212", but still had no success. I was defintely getting bigger, 20Mbps files, but without the quality.
I too had an issue with my Colossus and a moving horizontal bar. It was about 1/3 the width of the screen and slowly moved from the bottom to the top. Wherever the bar was the color would be off a bit too.
I found it pretty annoying so I contacted Haupaugge support via email and they mentioned that I should move the card to a slot farthest away from the power supply. Good advice (I think) but it didn't fix the issue.
The last thing they said to try was different component cables. The minute I changed them to quality set I had lying around the issue dissappeared completely and the picture was a sharp as a tack.
I mentioned that in my email to Hauppauge and they sent me out a new set to replace the ones included with the card. I'm surprised the stock cables 'leaked' because they are pretty darn heavy-duty.
At any rate, I get awesome picture quality from my card but I suspect you have the same issue I had. I'd encourage you to have another go at it - once I changed out my cables the picture was perfect and the horizontal band was gone.
It may also be important to keep the cables away from power cords etc.
Speccifically, this is what Haupaugge support mentioned about the 'banding'
"That sounds like some type of RF interference or maybe EMI. You might want to try moving the Colossus board away from the power supply in the computer in case. If your computer is plugged into a surge protector you can try plugging directly into an outlet to see if it is a ground problem. The other place you might pick up noise is over the video cabling."
