Oh, this should be simple to fix. Audio is exported separately by compressor, and imported as a separate file into DVD Studio Pro. So in addition to the MPEG-2 file that you already successfully created, you also need to export (from compressor) an audio file. Unless you have very specific needs (such as surround sound, or uncompressed audio for the highest possible audio quality), the common consensus is to use the Dolby Digitial (AC3) 2.0 format. You'll find a preset for it in compressor. It will generate a file with the extension .ac3 that you can import into DVD Studio Pro and assign to the same track that already contains your video.The video played well, but there was no sound. Did it not convert audio? How can I include the audio?
