You too :-)

What I see is perfect "still" quality. The problem is interlacing 
artefact's on  movement, just as you have clearly described. What I was 
trying to say was that there was absolutely no reduction in interlacing 
artefact's between interlaced 2x, and none. So doubling the field rate, 
and repeating the fields does not lead to a constant synchronization 
between recorded and displayed interlacing.  The effect is 
disconcerting, and is clearly noticable on all scene changes, as well as 
movement.

VGA to scart gives excellent quality, and the quality is also acceptable 
on movement using high quality deinterlacers, but the whole point is 
that we shouldn't need to de-interlace to display it :-)
