DVDSANTA stole my audio

I am using iso buster to convert BIN files to a DAT format which I then use dvdsanta on to convert to video files before I burn with Nero. However recently when I haave converted the DAT file with Dvdsanta, only a few minutes of sound are working at the begining, I have tried changing the compress LPCM audio option with no success. I haave looked around and not found any answers, Please help, I have burned too many coasters before I got the ASPI layer and media right, I can't go throught tht gain!

All comments will be greatfully recieved, thanks
