My understanding of it is, as Billy Batson says, the DVD audio is NTSC 29.97 (which I think is 23.976 fps), and same on the blu ray. The audio is synchronized to the video and both are referenced or locked to a common video signal. Video can alternately run at 24 fps frame rate but does not change speed which would affect sync if it did!
But 29.97 (for all intents and purposes, 30fps) is a frame rate and I don't think digital audio is really tied to a video frame rate even though I clumsily said as much in my earlier post. After all, both 24fps and 30fps still last a second
