I have been usiing VSO DIVXtoDVD for awhile now mainly to encode multiple avi's to burn to DVD when audio sync problems started occuring in every conversion I try. Just to try a test, I went back and encoded an old avi that I previously encoded and burned with no sync probs and the avi that encoded fine before all of sudden is out off sync now and it seems to skip or jump every 2 to 3 mins making the dvd unwatchable.
Why would this happen suddenly? is it a codecs problem? 
thx in advance
