From what we have seen, these two values have been working out: frame rate (23.976) and scan order (2:3 pulldown). At least for the test video when VOB converted to TS. The other is frame rate (variable), original frame rate (23.976) and scan order (2:3 pulldown). It seems that a variable frame is a false positive, even when the timecodes are all over the place. It sends one down the wrong rabbit hole.

As a side note, one of the DVDFab produced MKV files also resulted in a 3:2 aspect ratio when a VFR->CFR was done on it.

Oh, and it all comes down to what you said... DVDs can't have variable frame rate videos. It must either be 29.97 or 23.976 w/ 2:3 pulldown, because analog TVs only support 29.97 interlace video. Of course, that is moot with today's digital monitors/TVs.

IMHO, it was stupid that we kept the 29.97 frame rate when converting to digital broadcasting. I do not think there is an analog TV that wouldn't have been able to handle true 30 fps interlace video. But, that is moot too. That ship has sailed.
