Movie DeSynch issues explained

Okay, a LOT of movies run @ 23.976fps (frames per second). This is usually just referred to as 24fps, but can cause some issues w/Blu-Ray playback on certain TVs. Many video codec have been rewritten to now use 23.976fps. The problem is most if the audio codec have not. This leads to video @ 23.976fps while the audio is timestamped @ 24fps creating 0.024 time difference. It is unnoticeable at first, but will cause a movie to be 0.5-2 seconds out of synch by the end as the time difference builds.

This is yet another fine example as to why I don't want to support Mom in copying DVDs :) I told ya this shit was hard!
