Prolem with 23.976 FPS AVI file

[ho1]

I have a problem with a 23.976 FPS XVID AVI (animation) file on my PC. When it plays I see visible skips in the output. Could you please describe 23.976 vs. 29.97 FPS and tell me if this problem can be solved by a converting it to 29.97 FPS to or not.
In topic * I read that: "23.976 is the true NTSC DVD compliant frame rate"; So when I rip such DVD to an xvid AVI file and get 23.976 FPS (that has visible skips in video) is it a ripping problem, or it's because of the quality of the file? In animations this is even more visible, (I guess) because of the duplicate frames that were used to ease creation of it.
I've tried DGPulldown but it seems can not handle XVID streams, and also tried to do frame rate change with Virtualdub but it caused de-synchronization in audio/video.
Is there a software player that can do this on the fly, so the video runs smoothly on the PC?

There are two NTSC compliant frame rates typically found on DVD: 23.976 and 29.97 fps. Since movies are shot on film at 24 fps they are usually slowed down to 23.976 fps and have 3:2 pulldown flags that tell the DVD player how to produce the required 59.94 fields per second required by interlaced NTSC video. Less common are films that have hard 3:2 pulldown applied to create 29.97 interlaced frames per second that the DVD player then outputs as 59.94 fields per second. It's possible to have other frame rates and pulldown patterns (or example 25 fps and 3:2:3:2:2 pulldown) but the final result has to be nominally 29.97 frames per second and 59.94 fields per second. Again these can be via pulldown flags or via hard pulldown. DVD can contain pure 29.97 fps interlaced frames, usually from live events like sports and news. These have 59.94 unique half-pictures (fields) each second with two fields packed into each frame.

The way you treat each of those kinds of DVD sources differs so you'll have to be more specific about what you have.

And if starting with an XviD AVI, it's already too late to fix anything anyway. Maybe provide a short 10 second sample that shows the problem.

I've tested ConvertXtoDVD and it did a great job. It did a pull up automatically (different from its usual frame rate conversion) and the resulting DVD was comparable to the original NTSC DVD.
Thanks guys.
