quick and easy DVD burning
 

Hey!
I plan on getting Vegas 5 + DVD sometime later when I have the extra budget. In the meantime, I need to burn a DVD.
My DVD burner may have come with software, but I've probably long lost it. What software do I need to burn an .avi file onto a DVD and have it autorun as soon as it goes into a DVD player.
Prefereably something free or shareware. I just need to do one, once, then it'll be a while before I need to do more and I'll have my Vegas upgrade by then.

Also, which DVD format should I use?

Thanks!

p.s. as you already guess I'm on a PC...

Nevermind, I'm going for Vegas 5 +DVD. Bought a stack of +R and -R discs too.
