Don't think you've been following things. DVDs as such
don't have either an NTSC or PAL footprint unless the
originating material had.

I don't think that's correct. There are differences in the number
of scanning lines and frame rate on NTSC and PAL DVDs.

There are - but neither are *fundamental* to PAL or NTSC.

Okay... Right...


With regard to your comment -- which is something like
"there's no water in a glass unless you've poured water
into it" -- what sort of non-PAL or non-NTSC-format material
would you record on a video DVD?

If the material is sourced from a composite PAL recording,
it will retain the PAL footprint.

Now you've lost me. I didn't know that DVDs were -- or could be -- made from
composite sources. MPEG encoding wasn't intended to work with composite
signals -- was it?
