Those frames aren't repeated, they are blended together, part of the frame before, part of the frame following.
Ah, that's why I said fields
A field is half a frame - one field is the even numbered lines, the other is the odd numbered lines. By my reckoning there will be one "reconstructed" frame for every four full frames (eight fields), bumping 24fps up to 30fps - this isn't quite what I thought you were describing though, because:I think, although I'm not certain, that when a DVD player does the bumping up, it repeats one field for every four original fields (2 frames) - the order of the two fields in a frame is reversed each time a field is repeated, but because the frames are progressive this makes no difference.
Sounds like, the way they've done it, that you can just delete the offending frames (which might take a while), save as a 23.976fps AVI and import that into Vegas.
