Help...EXPORTING

I am trying to export a flash file (into Quicktime-I presume that’s best) and keep the high quality resolution that I have in flash.
This will later be run on either a DVD player or a Mac and projected in a constant loop onto a screen. I would prefer to have this available in a format that can be put onto a DVD.
However, when I export into Quicktime or QT video my file becomes grainy and ugly… Any suggestions?
Thanks to all.
Post Script: I’ve gotten the file into a swf format that looks good, can this be edited/turned into a usable format in a program like final cut?
