I thought 1 was out. 2 and 3 seemed in sync. 2 seemed a bit better on first viewing, but it's close. In my opinion, if the audio is one or two frames out it is unlikely to be noticed by most people, but three or more is usually noticed at some point in the film. I'm usually quite good with synch and often see commercial DVDs that look out of synch, which can be really annoying.
EDIT: Whoops! Didn't see that you'd posted the results. Now no one will believe me lol.
