I have been converting avi files to dvd using AVI2DVD for some time with no problem. I use vdub to extract and uncompress the sound and then run AVI2DVD and get mpeg file which I author using TMPGEnc DVD Author - no problem. However I have just come across an avi that plays in synch, but when I uncompress the sound (Fraunhofer IIS MPEG Layer-3) and resave the avi it goes out of synch. I have tried running it through AVI2DVD without uncompressng the sound but that too results in a mpeg file that is out of synch. Any ideas?? Please help.
