Whenever I import an NTSC DVD Vob file with a frame rate of 23.976, Virtualdub insists that it's 29.970, and it appears interlaced, when in fact the footage is progressive. This does not happen in Virtualdubmod. This does not happen to progressive content that's recorded in 30 or 25 frames per second. Interpolating the frame rate or running an IVTC filter do not result in the original image quality, either. What am I doing wrong? |

Please read this topic:

What you have is a movie with RFF/TFF pulldown flags. The MPEG-2 plugin acts on these flags exactly as a real DVD player would, to produce 29.97 frames per second output for NTSC television. That is by design, and currently there is no way to turn it off.
For this type of content you should consider switching to a different method using DGMPGDec and Avisynth. (That is what I would do.) Search the forums; the DGMPGDec approach has been covered many times.
