Advice on how to sync audio with video?

[leglessmoof]

I have seen many bootleg DVDs around (these are legal; i.e. NOT promoting warez!) containing audio and video from different sources. For example, Pearl Jam DVDs with video recorded from an audience cam and the audio from the official bootlegs. How does one go about syncing up audio and video from two different sources? I am looking to do some of this in the future, which is why I ask. Please post here or e-mail me at lelgessmoof@comcast.net with your advice.

Perhaps "bootleg" is the wrong word then? How about "audience-filmed DVD of a live concert?"

Regardless, the question still stands. Does anyone have any experience with synchronizing audio and video from different sources?
