I'm interested to know what software you guys like to use and how you render for best quality.

I use Sony Vegas Pro

I render NTSC Widescreen 24p SD. (720 by 480)

And I burn my projects to DVDs with Intervideo.

How do you do it?

Also Sony Vegas. Rendering is typically lower quality for web use.

Adobe Production Studio Premium (Premiere Pro 2.0, After Effects 7.0, Encore DVD, etc.).

NTSC Progressive Scan 7Mb VBR for DVD.
