This all matters. It matters a lot. It creates confusion in users
and I can only imagine what it has done to ff libraries (and
how they have been patched to compensate for this bug).
Do you think the issue you see is also reproducible with
ffmpeg or only with ffprobe?
I have no idea, Carl. I've never used ffmpeg.
Then why don't you believe that the issue you see is that
FFmpeg does not "support" soft-telecine when reading
program streams?
Because out of hundreds of region-1 DVDs, I've found only 2 that don't
use soft telecine, at least for the main feature. If ffmpeg didn't
support soft-telecined VOBs as input, then it could not be used to
decode so-called "NTSC" DVDs,
You misunderstand:
I didn't claim that FFmpeg cannot "read" the decrypted vob files
in soft-telecined dvds, I claimed that the soft-telecine feature in
such vob files is not "supported" (but ignored) because it is
only needed if your display hardware needs it and such
display hardware cannot be used with FFmpeg (or any modern
video player).
It is of course possible that I am wrong, that the flags are not
ignored but incorrectly processed but since they aren't needed
nobody complained so far...
Note that other free vob demuxers and other free mpegvideo
decoders exist.

Well, I'm not aware of them. I'm aware of only ffmpeg. I'd like to make
some comparisons. Do you have any links? Or do you know their names so I
can do a web search for them?
Thanks!
