I downloaded the necessary updates for playing DVDs on my new machine with Asus A8V motherboard and a GeForce 5700 video card using the Nvidia driver. I get white streaks from text that is in white or with other light colors and some of the graphics in light colors. I get it even with the Kaffeine splash screen. Don't get it with dark colors that I can see. I also have it running on my Dell Laptop and it does not show up. Does anyone have any ideas on what is causing this or what to check first? Art
