But I can add the ratio information to the VFR-->CFR encode easy enough.

I'm going to look at the timecodes more closely to see where the anomalies are.
Well... it just get's weirder when you look at it. Since the original rate was 23.976 there should be a little less than 42 milliseconds between pictures. But it appears to alternate between 33-34ms interval for one picture, followed by a 50ms interval for the next. That would average out right... but I've never seen anything like that. Then the last two frames have an interval of 0ms. I had my code count the frames... and the total seems right.
