Hi-res interlace will always flicker on a TV. However, there are tricks that you could reduce it.
1. use related colors and no thin horizontal black & white lines
2. turn down your contrast on your TV
3. if you are familiar with art programs and you use graphics that flicker in your background, you can reduce the sharpness. Reducing sharpness allows other colors to blend in a little and help reduce the flicker like a slightly out-of-focus camera.
To eliminate the flicker, simply select a screenmode that does not have the interlace feature.
