What's the cheapest way to show a QuickTime video at an exhibition without burning it to a DVD?

I have a short animation in a group show in Boston opening next week. The piece was constructed to be run off of a hard drive through quicktime pro. The gallery wants to show it off of a dvd because its easier for them, but burning it to a dvd really degrades the quality. I am looking for the easiest/cheapest way to run the piece from quicktime—can I do it off of an ipod? really cheap laptop? any suggestions?
