DVD2SVCD not working if audio delay changed with YAAI

I have an XVID AVI file which the audio was out of sync, so I used YAAI to edit the audio delay. When I try and convert it to DVD format with DVD2SVCD it fails with DVDAuthor giving this error:

DVDAuthor::dvdauthor, version 0.6.11.
Build options: gnugetopt iconv freetype

ERR: Error opening C:\Documents and Settings\Aaron\Desktop\Movies\MPlex_Muxed_File00.mpg: No such file or directory

Probably becasue there is no MPlex_Muxed_File00.mpg being created. Now if I use this same AVI file that hasn’t had its audio delay been edited with YAAI, the AVI gets converted to DVD fine. Any ideas?
