Exporting for creating a DVD in iDVD

Hello,

What is the best conversion settings for taking a .mov and re-exporting it in order to use it to make a DVD on a MAC with iDVD?

I exported it with H.264 video codec (on a Quicktime preset) and while it exports and runs, when I make a DVD with it, it won't play on other DVD players.

Any help would be sincerely appreciated.

Regards,
