Ok, nice to know that you got it working...

Could you provide a sample image ?

The image is an interlaced image and it's constructed by joining two 
consencutive frames, so that's what
can cause some "distortion" in the image with fast-moving objects.

The horizontal lines I'm talking about don't have anything to do with 
the content of the image,
they just appear and disappear. The black lines always start from the 
left edge of the picture
and it seems that the pixels from the start of the lines get somehow 
moved forwards to the center of the
same line of the image. (eww, this is difficult to explain :)
