The "video stream" templates create just that -- a video stream. If you want to include audio in your file, then either a) choose the DVD NTSC template, which embeds the audio as MPEG audio, or b) choose the video stream template, then click the Custom button, go to the Audio tab, and check "Include audio." Set your audio settings as you want.

That said, if your intent to is to make a DVD using DVD Architect, then forget most of what I said above because you don't want your video and audio to be in the same file. Or, rather, DVD Architect doesn't want it that way, and it's less hassle in the long run to give DVDA what it wants. ;)

1. DVDA likes the video and audio to be in separate files. If you give it one file, DVDA will have to rip them apart and re-encode the audio stream.

2. DVDA doesn't like MPEG audio. It likes AC3 and WAV PCM. When Vegas creates an MPEG2 file with an audio stream, it uses MPEG audio. Ergo, don't let Vegas include an audio stream in your MPEG2 file if you intend to use that MPEG2 file in DVDA.

To output files to be used in DVD Architect, do your video using one of the DVD Architect video stream templates and then do a second render for your audio using Dolby Digital AC3 or WAV PCM. Give the audio file the same name (other than the extension) as your video file and put it in the same folder as well. DVDA will find the audio when you add the video file.

Note that these are "best practice" suggestions. DVDA will go ahead and accept an MPEG2 file with MPEG audio embedded, but it's my experience you're better off not going that route.
