fixing audio sync on burned dvd (video ts).is it possible??

[mr.sean]

i downloaded gumball 3000 movie in avi format.it played perfectly in windows media player and power dvd-no audio sync problems.after encoding it with mainconcept and burning to dvd with copy to dvd,the audio is about 1second out!
like a doofus i've deleted the original avi file,so i can't re-encode it !!!
is there any way i can extract the bare mpeg from the video ts folder to enable me to sort out the audio sync issue?
or is there another way round this problem? i can't find the file now to even re-download it!!
any help would be greatly appreciated
thanks

u have to demux the movie and then u get the sound seperate from the video (.ace and .mv2 I think...) then just play around with an audio editing tool and hope for the best when u mux them back toghether...
