How far off does the audio have to be before it doesn't look/sound right?  How 
accurately does the typical movie process get things aligned?

We are used to a delay of several to low 10s of ms.  Somewhere in the 20-100 
ms range (depending on how good your eyes are) you can't see the speakers face 
well enough to help decode what they are saying.

Are people sensitive to the sound being early?
