I put an audio file (.wav) in compressor to have it transfert in an ac3 file. Compressor did the job perfectly without error message but when I import the ac3 file in DVD SP and double clic on it to listen to it, I hear nothing. What happend to the audio? The wav file had something in it but as soon as I transfert it in ac3, nothing at all. Can you axplain me what I did wrong and if it's possible to do that transfert. It will help me a lot.
