On my card, I have s-video out going to an rf converter, then to tv coaxial. My problem is that when i watch something in PowerDVD in fullscreen mode on my tv display, the picture looks garbled. when windowed, the picture looks fine. I changed the screen size and position and put the flicker filter to the max, but it still looks bad fullscreen. Almost like a bad deinterlacing or something. I have the newest drivers, also. How could I fix this?
