I was referring to normal movie NTSC DVDs. These should have the flag already set, shouldn't they? I think hardware players play them with telecide (don't have one to test), but software players ignore the flag, did I get that wrong? Anyway I will try to play with the flag and see what happens... UPDATE: didn't work, I ripped a stream from one of these DVDs and ran it through pulldown.exe. Intervideo Decoder at least still does only progressive frames...and even if it worked, it wouldn't help me with my problem: I am trying to have smooth playback of NTSC DVDs on either PAL TV with 25 fps (fps conversion necessary: DivXG400 forced into the filter chain only works for 2 ch audio, otherwise video is slow motion, DVobSub forced into the filter chain: force fps fails on mpeg2-content, anyone knows any other method for on the fly fps-conversion: a player that can be set to fast-forward at 1.0427 with audio or something?) or on NTSC TV with 29.97 fps which would need on the fly telecine by the software player/direct show filter...

I believe the graphics card, and TV-OUT perform these functions (hence the ability of selecting PAL/NTSC/etc televisions in Control Panel options), and not the software DVD player.

@ adam Software DVD players DON'T telecine, they keep the 23,976fps without any processing (thanks god it's that way!) As int 21h said, it's the TV-OUT that makes 29,97fps output to your TV. If the Soft DVD player was to telecine and then to deinterlace, you'll see a lot of blends and jerky motion during panoramics on your monitor. BTW, as said above, there is (too) many NTSC DVDs that aren't encoded properly in 24fps, especially anime DVDs. So 99% is way too exagerated, I would rather say 99% of hollywood movies ares encoded properly and only 5% of all anime DVDs are encoded properly. Why is that? don't know! Does 24fps encoding costs more than "normal" 30fps interlaced encoding?! does anybody know?

Ok then my mistake. Dj Bobo, judging from your avatar you may take offense at this but I purposefully did not take anime into account in my % estimation. I honestly think grown men watching cartoons is silly; Simpsons and the occasional Disney/Pixas movie being exceptions. Alot of things that originate on broadcast tv; Friends, Seinfeild and certainly almost all anime is pure ntsc or some form of hybrid, however the vast majority of theatrically released movies are stored on dvd at 24fps. That's all I was getting at.

Oh give me a break, I'm hardly a troll. I thought it was pretty clear that I did not intend to offend anyone and I also thought it was pretty clear that I was only joking. I guess from now on I'll have to add a disclaimer to my posts so that there is no more confusion. Also I don't see how assuming someone is an adult is insulting. Believe me the last thing I intended to do was start a flame war about anime of all things. Can't a person just say something in passing? Geesh lighten up.

Still three questions :) 1. Is there any way to set any software-player/filter to do telecine on 23.976 ntsc source? 2. How can I check, if my Matrox G400 DH performs telecine or not, when I set it to NTSC-Output and feed it 23.976 fps input? Judging with my eyes is not clear for me...any way to force it DO telecine or DON'T DO telecine? 3. I am still in the following dilemma with my DVD filter-chain trying to speed up 23.976 fps-discs on the fly for display on a 25 fps pal tv: Intervideo Navigator and Cyberlink Navigator crash Zoom Player V2.90 Final. DVD Navigator resets DVobSub fps-conversion. :( Intervideo Video Decoder reports wrong fps. -> DVobSub fails. Cyberlink Video Decoder reports correct fps, and works with DVobSub (connect indirectly Video Decoder to Overlay mixer with DVobSub loaded), but DVD Navigator still is the problem (see above). workaround for now: Force DivXG400 into the chain for fps-conversion and set intervideo audio decoder to Dolby Surround, multichannel doesn't work with divxg400! :( other workaround: rip movie to harddisk to play from there and use Cyberlink video decoder together with DVobSub to set fps! (No Navigator needed) Both workarounds are not optimal...any help?

There is too much speculation and very little real and prowen fact. One thing more: there is lot of movies on DVD which starts with logo of publisher, and that logo is NTSC (according to DVD2AVI), later, when is movie itself it is FILM. But it's not possible that in 1 VOB we have 2 different framerate (29.97 & 23.976). So it can't be at 23.976 I think.
