I have mythtv running on RedHat 8 with mysql 3.23 and mythtv 0.8. My video card is a pixelview with the 878 conexant chipset. I can hear sound but the video is just snow and ghost images. I have the video set to /dev/video0 and I do have /dev/video, /dev/video0,1,2 but only /dev/video0 seems to work. Any ideas why video is not showing?
