Rendering sound & video separately

Yesterday I burned my first ever DVD using DVDA - it was a breeze. To do it I went by the manual and this brings me to a question.

Following what it says in the manual (Chapter 3, in the section about Preparing Files for DVD Architect Software, page 26 I think) I went back into Vegas Movie Studio and rendered my movie as NTSC MPEG-2 using the "DVD Architect NTSC video stream" template. Now in the same section of the manual it says I need to render the audio separately, which I did as a PCM WAV file. So far so good.

However, when I switched to DVDA and dropped in the MPEG file, it played with audio in the preview - so I burned the DVD and tried it out in my DVD player and it worked just fine, audio and all. It never asked for the WAV file and never implied that it was needed.

So, did DVDA automatically locate the WAV file without needing to be told? (the MPEG and WAV files are in the same directory and have the same name - only the file extensions are different, so it would be easy for DVDA to assume that the files are related). Or, is the audio data already in the MPEG file so that the WAV isn't needed (in which case, why does the manual say that the audio needs to be rendered separately)?

If the WAV file and the MPG file have the same name and live in the same directory, DVDAS (and DVDA) will normally automatically find the matching audio when you bring the MPG in.

That explains it. So in future I will make sure I remember to always render the audio separately just as the book says.

Thanks! :)
