Resize then to 788/1050 then cut the black borders and you'll end with some strange number of pixels but quadratic.

Thanks! After a 2 month break to clear my head of all this, I realize what you're talking about now. So I assume it looks like ITU, but 788 pixels wide with 10 pixel wide black ( or some say it could be white) columns on each side? And I assume the black or white columns would be overscan on an old 4:3 TV, same as ITU?
The DVDs I have (Old Doctor Who from the 60's) seem to just be the whole film frame ( you can actually see the slight rounded corner at the bottom left sometimes ), so I'm assuming non-ITU and 768 pixels, and the 3 or 4 pixels of black you sometimes see are just sloppy capture as they went beyond the frame itself on to the actual frame holder. I now understand that the digital width is what "fits" into 720x576 non-square pixels, and the "digital pixel size" varies according to different companies. i.e. BBC's digital "pixel width" is different from most other standard "digital pixel widths", so 788 "BBC pixels" fit into 720x576 the same as the "standard 768 pixels" fit into 720x576.
Found a good post on this here:

@mods - Sorry for the double post, but it's been two months since my last post.
