[HELP] Any ideas on how to handle a variable FPS source?

"DVD source" -> then the video should be cfr
No clue what you are doing,... share details,..

That's what I was thinking, but the evidence so far shows otherwise. And I also believe my eyes: some parts of that dvd actually look smoother than the others.

Here I made a short video demonstration of that: in the beginning it shows as ~60fps even though frames are obviously doubled, there are also smooth fragments in the beginning and then the actual concert is fluctuating around 30fps which is just weird.

What kind of details do you need? Debug from Hybrid of some level?
