I know a bunch of people on here like to make custom DVDs and I saw this offer for a free copy of WinX DVD Author:

It's normally priced at $30. I have never used this or heard of it before, but for a no-hassle free download, I'll give it a shot.

On Windows, I currently use TMPGEnc Authoring Works 4 for quick DVD authoring. Despite spelling errors in the UI, I find it to be really nice and simple.
