Pixel Format
Can anyone explain to me and ‘my gang’ how it is that 4×3 and 16×9 have the same pixel format (720×576)?.Are the pixels different size/shape?.

Well, if we are talking about a letterbox effect, then the pixel layout is all the same except the bars on top and bottom are made up of black pixels.

Ah! Just noticed pixel aspect ratio is 1.0926 for PAL DV and 1.4568 for PAL DV Widescreen. Do I sound like a nerd???.

The pixels ARE a different shape…DV pixels have a .9091 aspect ratio; they’re a little bit taller than they are wide. HDV pixels have a 1.33 aspect ratio; they are short and wide.
But that’s different than your horizontal and vertical pixel count. All flavors of HDV have more pixels than 720×576.

I’m presuming Doug, when you say HDV you’re meaning ‘High Definition’ rather than DV Widescreen (not HiDef)

Yes.
