Ok. I see from log that Hybrid attempts to ignore 24fps metadata. Nice!
Prefering container (29.97) over stream frame rate (23.976)
Hybrid see it as "29.97/CFR telecine"
With some MKVs it works (i can see 2 interlaced, 3 progressive frames pattern).
But with other MKVs it don't works (i see it in preview as progressive video).
Hybrid see it as "29.97/CFR telecine" or as "24.204/VFR top field first"
But if i import DVDs originals of same videos, Hybrid see it as "29.97/CFR telecine" and i can see 2 interlaced, 3 progressive frames pattern.
Yep, seems that PAR problem is due DVD.
Original VOB in mediainfo looks like this:
Pixel aspect ratio 1.580
Display aspect ratio 2.40:1
MakeMKV converted it to:
Pixel aspect ratio 1.185
Display aspect ratio 16:9
Original display aspect ratio 2.40:1
So in summary - that telecine problem consists from two independent parts:
1. Some wrong metadata in first VOB file that differs from other VOBs in DVD and that force Hybrid to read it as VFR.
2. Some unknown metadata in MKV that force Hybryd preview it as visually Progressive looking content.
I can reproduce both problems when remux DVD to MKV with MakeMKV or with MKVToolNix GUI.
