The frames are shifted +- 0.5 lines so you nearly get full resolution.

I even did some photographs: (at my TV) I didn't see individual lines, it 
looked more like a homogeneous frame every 1/50s.

Also some "real world tests" like scrolling text (cnn,...), sports, ... 
didn't show side-effects of interlacing.

I own a >50cm Sony Trinitron TV. And I have seen other TVs, too.

Maybe that's the reason. PAL has higher vertical resolution and better 
chroma, so maybe those "jagged edges" are unique to NTSC.
