NTSC SVCDs and DVDs have to be 29.97fps. However, it's possible to encode them at 23.976fps progressive and insert rff and tff flags which will tell the player to perform a 3:2 pulldown during playback, making the video 29.97fps for your NTSC TV. The same procedure is being used for most NTSC DVDs.

Go to the commandline and type "pulldown video.m2v" where video.m2v is the demultiplexed MPEG-2 video stream. . This will create a file called pulldown.m2v which is the file you're going to work with now. You can now delete video.m2v.
