NTSC-based frame rates (23.976, 29.97) are represented incorrectly in MLV file format.

I am working on my own decoder and I noticed that the values for sourceFpsNom and sourceFpsDenom do not represent NTSC-based rates correctly.
Instead of being 23976/1000, for example, it should really be 24000/1001. This may be trivial considering the duration that you the camera can typically record, but this can cause a drift in streams after hours.
