[MEncoder-users] audio delay

[Uzu Maki]

nice -n 3 mencoder -oac copy -delay -1 -ovc copy delayed.avi -o "remuxed.avi"
doesn't work... but it was worth the shot...

is there another way to correct audio delay ?
I tired to > in .wav, cut and re encode in mp3 but it doesn't work either...
I get a progressive delay throughout the movie...

thanx for your help!
(of course I can just watch it with the -delay option but...
it's for my non-linux-user niece...)
cheers
