I'm assuming that the 24KHz you typed is a typo and you meant 44.1 KHz (right?)

I'm not doing a lot of video, but if I recall, some video standards run at 48KHz instead of the 44.1KHz that most music compatible disc used. Could it be that when you recorded your audio along with the video that it is pulling it to that sample rate. Or the other way around where the video is pulling the audio to that sample rate during playback. Try to separate the video from the audio and see what happens.
