Yes! It's indeed very hard to get them sync once they out of sync.

I think I am using the similiar setup as you, DVD2AVI, Nandub w/ 
Divx. So as you said, if I fill in the /first video offset/ value 
into Audio/Interleave..., /Delay audio track by [] ms/, it should be 
sync?
/First video/, /Eariles video/, these two terms are still confusing 
me. :-)
