As far as I know, this option alters the framerate of the video to try and match your display's refresh rate more closely.  As you probably know, if you alter the framerate of a video stream, the audio must be resampled to match.  If passthrough were allowed in this scenario, the audio would gradually drift out of sync because you've sped up or slowed down the video without adjusting the audio.

That sounds very reasonable and logical, thank you very much for answering.
