Cant get this Intro Movie Clip to run normally for the life of me

Hey guys.
I just got done designing this intro that is supposed to go on to a CD for this client. The flash piece is meant to be a interactive CD. The Intro has a lot going on lots of bitmaps going this way and that and as such is im sure kind of heavy on a processor. It runs perfectly on my computer(But again it always does) but on other computers its much slower so it throws off the music completeley. I see my only options as being to tone down the amount of stuff moving which seems kind of ridiculous cause its not that much or making the intro a quicktime movie that segways into the flash. Any help would be greatly appreciated.
thanks guys,
Chris
