There are (at least) three parts to the answer.

1) The camera settings determine if the source pixel dimensions are 4:3 or 16x9.

2) The Vegas Pro Project Properties determines how the Preview will display.

3) The Render As template that you choose will determine how the video is output.

There are so many steps along the way where this can be determined or switched. That camera can record in both 16:9 and 4:3, so make sure the camera is set to 16:9 widescreen. In Vegas make sure you create a widescreen project. Make sure you use the appropriate widescreen rendering template when generating the MPEG2 file. In DVD Architect set the project type to widescreen there as well.

And, your DVD player and TV will both have options to override what the DVD says and play it as either 16:9 or 4:3, but they should both default to the settings in on the DVD.

You asked this over on the Cow. Same answers here as there and I agree here with the answers given
