Burning DivX/XviD to DVD?

[Korgoth]

Hey guys,
I could use some help... I'd like to burn some internet videos (.AVI) to a DVD so I can play them on my dvd player on my T.V.

I have no idea what I need to convert these files to for burning, or even how to go about burning them. So could you guys tell me what I need to get started, and where I need to get started?

Thanks!
