23.976 fps source file?

[Greyfist]

I'm brand spanking new to all this, decided this morning to try my hand at putting some of my old video files on disk so I can play them on TV. Only, the source file doesn't fall into any of the categories I've seen, 640x368 resolution and 23.976 fps Divx 5.0.2 file. I've ripped the audio tracks with VirtualDub, converted the video with TMPGenc, and used CD-Maker 2000 to burn them onto disk.

Everything sounds good, looks good, but the audio is faintly out of sync with the video in most places, and hugely out of sync in certain spots, as in an entire sentence will go after the lips have stopped moving. I tried encoding the file with both standard NTSC and NTSCFilm under TMPGeng, and both had that problem, with NTSCFilm also having the problem of the video visibly speeding up every few seconds before slowing back down.

I have no idea what I'm doing wrong here, any advice that anyone can give would be hugely helpful.

In fact, this is the really weird part for me, when I play the Mpeg files output by TMPGenc on Windows Media Player, there's no out of sync audio, no speeding up or slowing down of the video, everything is precise and perfect. What on earth is doing this?
