Yes of course. The brain is used to dealing with audio lag at varying
distances. I was playing around with VLC which has a sync control. It
seems I could set it to be off a bit but my brain seems to correct it with
in some seconds... Or maybe every time I change the sync the audio and
video restart from a known point of sync and then drift...

As you said before, the brain notices leading sound much sooner than
lagging sound. That would be the way it is in nature. The drive-in
theaters I have seen have in-car sound (often using the car's radio), so
the delay is minimal. I wonder if indoor theater operators set the audio
ahead just a bit so it hits the second or third row in sync. It would
probably mess with the surround sound too much. I will say I have not
noticed sync problems in the theater even though we always sit at the back
as my son doesn't see well above horizontal.
