Edward,
Unfortunately, I can’t find .wav as an option unless I click a few advanced features in what seems like a convoluted way to get there… and once it’s done rendering to .wav I can’t play it on my PC media player so I doubt it worked.
A friend told me to use .avi instead. It appears to get my video and audio out of Vegas and into DVD Authoring. I’m now preparing files to write to DVD thru the DVD authoring S/W which is now rendering.
Thanks!
