This is unrelated to this issue:
FFmpeg simply ignores the flag and interprets the
input as progressive.

I live in PAL-country but from user reports and
samples (like the one in question) I know that
this unfortunately isn't true;-(
This whole issue is about vob files that contain
both progressive 24000/1001 and (hard-) telecined
30000/1001 video in the same stream (with actual
switching frame rates).
It appears to me that decimate should detect the
frame rate changes and not drop anything for the
progressive content.
