Mini DVD media question....

I am thinking of putting my demo reel onto mini dvd instead of a full fledge DVD and offering a promo dvd service for my clients that would be put on mini dvd. Has anyone burned anything to mini dvd and if so how was the compatibilty with DVD players and CPU DVD players.

I would like to offer this service along side regular DVD coping services. The main reason I want to use mini dvd b/c they are small enough to fit in your pocket and can go in a DVD player and/or a CPU. Thanks.
