ok i got this star wars divx

i exstract teh audio useing v.dun. then encode useing tmpg,

after i burn it it slows down and audio gets out of sync on my stand alone fbf player.

when i do this same file useing panasonic encoder, version 2.51 its fine. sowhats the deal with tmpg, all of a sudden its well dodgy, cus all my encoding turns out the same.
