hi, I'm ripping some DVD karoake to SVCD 2200 avg - 2496 max, but is getting a grainy picture at the scenes where the person is on a liferaft over water in a distance. when the scene is just close ups of people, the picture is fine albeit a little blurry. I'm using CCE with settings at 15 image quality, and anti noise filter set all the way to maximum at 32. Any help will be much appreciated.
