Now, this made a difference.  The default option in that menu was 
detect.  Manually selecting progressive made no difference, but 
selecting either version of interlaced did so.  It didn't look as good 
as what I would expect from a 720 or 480p signal, but it did a lot better.

Why, I don't know.  I'd almost say that the old programming is being 
dumped on the digital side as a 480p program without doing any cleanup, 
if that's possible.

Or I may be talking out of me bum, not sure which.  :-)
