Sorry, I meant "mp3lib" instead of "mp3lame".

The improvement was that rather than having the A-V display cycling 
between +/- 0.010 it almost always stays between +/- 0.000. That was the 
same thing I saw happening on files using the decoders you patched.

You're right, though, it actually appears to have been from 
outbuf_delay_v2.diff. I didn't have much time for testing last night and 
wasn't being careful.

So, that means the improvement to DVD sync I saw was actually from that 
other patch and not from this one. ...though I still don't know why the 
DVD gets improved sync and the corresponding dumpstream doesn't. I did 
find an mpeg file that shows an improvement from this patch, 
specifically, so it looks like both of them are an improvement.
