Rich, I like this very much, we need to find a way to integrate it into our MEncoder documentation finally. Guillaume, does this sound like a task for you? I have just reread the guide again and found a few more typos and minor glitches, here it goes: On Fri, Apr 01, 2005 at 02:13:49PM -0500, D Richard Felker III wrote:

Your choices for lavc audio are mp2, ac3, and various adpcm formats
I think you are not referring to the option names, so I would capitalize MP2, AC3 and ADPCM.

The so-called "three-pass" encoding which MEncoder supports has been reported to cause A/V desync. This will definitely happen if it is used in conjunction with certain filters, therefore, it is now recommended NOT to use three-pass mode. This feature is only left for compatibility purposes and for expert users who understand when it is safe to use and when it is not. If you have never heard of three-pass mode before, forget that we even mentioned it!
Is this still valid? I remember Loren doing a lot of n-pass work, but probably it only applies to x264, dunno.
