I can run xawtv (and zapping) grabber mode, but I would much prefer overlay (less overhead). When I try overlay I get a wierd cyan screen with some green square looking things - sometimes there is part of a scene, but nothing moving. I've tried two different cards (one ati tv wonder and an older hauppaugge card - both worked fine in overlay mode under Mandrake 9.0). I have a GeForce4 MX 440 card and I am using the nvidia-glx-1.0.4191 and nvidia-kernel-1.0.4191 versions of the nvidia driver - I have tried using the nv driver as well to no avail. this is the Module section in my XF86Config Section "Module" # This loads the DBE extension module. Load "dbe" # Double buffer extension Load "v4l" Load "extmod" # This loads the Type1 and FreeType font modules Load "type1" Load "freetype" # This loads the GLX module Load "glx" Load "dri" EndSection
