I encode all my PAL-Speedup25p-from-film-24p DVDs as 25p with HC since then
and am happy with the outcome on different setups.
To flag Progressive Sequence as: no
seems to be the vital part to be DVD compliant.
Yes, I would follow this.
Given the fact that PAL and NTSC are field-based
and the main video connection 1995 was the yellow Cinch connector
carrying the composite video signal in interlaced sequence
there was no need to allow an encoding parameter to be set to an untransmittable value.
Otherwise, DVD players should simply skip this value if set to Progressive sequence.
But it made a visible difference on my setup...
All pulldowns, 3:2 (23.976p Film on 29.97i NTSC),
Euro (2:2:2:2:2:2:2:2:2:2:2:2:3 24p Film on 25i PAL) come out a bit borked on this particular combination.
To encode and flag the progressive frame as progressive frame came out beautiful,
player will have to perform 2:2 pulldown to output as fields via Composite anyway.
A progressive-capable player may probably output such encodes as progressive if this is allowed via HDMI.
I can't tell exactly, but reflagging tests showed an advantage in certain player/TFT-combinations.
To encode and flag progressive material as interlaced (no matter if tff=1 or 0)
came out less optimal encodingwise.
On playback player will follow tff/rff flags anyway.
