@chofreeze: For me, scanlines help with noise and dither. You may benefit from moving to composite which should help to remove dither. Review this video, especially at the one minute mark Composite vs RGB. I would try composite and see if it looks good to you. You’re already on 2x 4:3 generic which would soften then image. You could try enabling Sampling->upsample2x (http://junkerhq.net/xrgb/index.php?title=OSSC).
