It outputs the 24fps, and it's up to your videocard to sample that

It's not synced to the video refresh rate, but that's not "missing
frames".

No, and if you did, how do you expect it to magically handle/fix the
audio?

If you card/driver supports OpenGL, -vo gl -vf tfields can improve
the situation somewhat, at least halving the effect, and should work
aproximately like film2pal telecine.
