Still fearful of breaking threads by responding, I just want to say thanks
to all the thoughtful and thought-provoking responses. My value system - in
line with some of those expressed - is mainly conservative, meaning 1) to
preserve the final material as close to the original content as possible,
whilst 2) catering for most prevalent playback systems. Which, as was
pointed out (by Phil Ehrens I think) may be mutually exclusive goals.

Be that as it may, my source is interlaced DV, and having tried to
RTFcr at ppylittleM of my Sansui DVD 3500, it states that the "component video"
connectors can be configured for either "YUV: ...analog component video
format when connecting to Y/Cr/Cb terminals" or for "P-YUV: set progressive
Y/Pb/Pr signals. Connection same as Y/Cb/Cr." The former (YUV) therefore
seems to be interlaced, and is the setting which works for my CRT, so I'm
happy to preserve interlacing.

In case anyone's interested, here's an exhaustive if not quite scientific
article on the nature of and investigation into various players of
"progressive scan DVDs":

Kind regards until later,
