Some added information about the problem. I am not seeing it when working in SD codecs, just HD. We usually work in DVCPRO HD and Apple ProRes 422 (HQ) when working in HD.
The 14 frames seems to be an average. It is not always exactly 14. It is only a REAL problem when I want to correct something already on tape and I have to re-output the entire show since it is not frame accurate.
