Video and subtitles will be excluded.-c copy enables stream copy mode. This copies the audio and does not re-encode it. Remove -c copy if you want the audio to be re-encoded.

You can try using PgcDemux to first demux the VOB, then use BeLight (just drag in the BeSweet files over) to convert the extracted audio to MP3. The audio in VOB files is most likely AC3.
