The picture posted created the black lines, they are not in the video. The actual problem is what you might call aliasing. It seems like some of the fields are a blend of two fields. Yes, it looks like the top fields are ok and the bottom fields are a blend of the top and bottom fields.
A quick solution would be to deinterlace with qtgmc.
Another idea is to try a subtraction.

Ok here's what it is, I suppose you would call it a blend deinterlace. There 3 clean progresive frames followed by 2 aliased frames. It seems these came from the original combed frames of a 3:2 pulldown sequence. They've been blended so that the top and bottom fields are one.
