In reply to:

Flicker is associated with this technique because as the phospher glow from the first pass will typically fade slightly on the second interlace pass.


This is true on computer monitors because of the demand for quality diferrence between the monitor and a conventional television. The pixels on a monitor are very fine and the phosphor glow fades very quickly. The second interlace pass doesn't draw before the first pass has faded (and the image flickers).

If I recall, conventional television doesn't suffer from this problem. We don't typically notice the flicker effect on TV because it has such blurred and enlarged pixels, and the phosphor glow takes longer to fade. This is not ALWAYS true (apply a little CYA on the surface for good measure ).
