Mini-DV widescreen to dvd

I recently purchased a Panasonic PV-GS80, mostly because of it's excellent 16:9 record mode. The TV I use most is 16:9, so that is what recording mode I use However, after burning the video to dvd, I was hoping that it would appear in a letterbox format on a 4:3 TV so it wouldn't squeeze the image, but unfortunately, that's exactly what happens! Is this something that can be adjusted? (i.e. a widescreen movie will have letterbox bars on a standard television, but when played on a widescreen tv, it's full screen)
PLEASE HELP!
Thanks

 

I'm using Vegas 7.0, and the way to do it in that program is as follows:
Create a 16:9 project
Render it as an NTSC (or PAL) DV widescreen avi.
Create a new project thats 4:3 and drop the rendered 16:9 avi onto the timeline.
Render the new project using a 4:3 template.

What software are you using anyway?

 

Thanks, I'll try that software. I am using Sonic right now.

 

I'm not familiar with Sonic at all. But the process actually sounds generic enough to work with any program.

 

Where can I download the software, and do you remember how much it was?
Thanks again.
