What is the proper manner?

I noted this in one of my movies too, and in my current A-V sync code I
use, mplayer syncs very quickly. But the correct way could be to start
playing the video without sound and start the audio later. That should
not be that difficult to add to my A-V sync code. The current standard
mplayer code always start audio immediately and sync video to it.
