Just tried it here with the vic app on a 2.2.18 kernel swapping between the bttv-0.7.57 inards and 0.6.4h. We were unable to see it _fix_ the grainy scan lines. The description does seem very similar here with the effect of motion on the lines. Xawtv does not show any problems like this with either driver series. > BTW, I havn't noticed anything wrong with the color.. maybe because my > webcam, which I pay more attention to then the tuner, is only b/w. We believe we have the color problem we had figured out. A slight shadowing on anything was being picked up by the camera, and vic was processing that change and sending it through. So even though there was no movement in the camera field, the slight shadow changes from curtains moving or people off camera were giving this effect. The graininess remains :(. From what I can get from the vic code, it looks very similar to other code being sampled on this listserv. I am changing a few things that people are suggesting here, but I have not seen any positive result. It does seem like the application (vic) is not grabbing the image very fast/often, so maybe more horsepower will help :)? > Thanks! > -Moses Later, JES -- James B.
