Do you have fields or duplicate frames? If you have duplicate frames what I did to solve it on a recent job was this:
Take the 59.94 footage with duplicate frames and put it in a new 23.976 (also try 23.98 if the first doesnt work) and you should have your original 24 fps footage without duplicate frames.
If you need to have 59.94 footage without duplicate frames then you'll need twixtor to create new inbetween frames for you. To do this turn on the "Preserve Frame Rate" option in the comp settings and drop this comp into a new 59.94 comp. Add twixtor and set the frame rate (in twixtor) to 23.976 (or 23.98) and you should have a 59.94 clip without any duplicate frames.
Of course this is assuming that the footage has not been retimed in any other way.
Yeah, the problem is that there seems to be some re-timing done in the footage...That is why the duplicate frames are not consistent clip to clip... The reason I asked was because I am rotoscoping these clips and the duplicate frames just mean duplicate mask kf's. If I could get rid of them procedurally, I would be saving myself some time.
For some reason I've always thought timeRemapEnabled was read-only. I've checked on previous versions of the scripting guide and this attribute is actually read-write from the beginning of AE scripting Thanks Lloyd.
