[MPlayer-users] crackling sound on a 3 pass divx

[christopher j bottaro]

hmm, i think setting the input gain to 9 is what caused the crackling.  i just 
ripped the first chapter without -lameopts vol=9 and it sounded fine.  i'm in 
the process of doing the whole movie now, will report findings tomorrow.
