Sound troubles...(music wont match up)

I have a music soundtrack that I have put in my flash movie and I sync. it with the actions, but when I go back to it later, it is all out of sync. and needs to be fixed again. I am using the " event " style of sync. I understand I may have to use “stream” but then the music sounds like absolute crap.
I really need help! thanks!

if you really need to sync sound then you should use director and not flash.
don’t hate the messenger, but flash doesn’t sync sound with very much accuracy.

What is director??
And why does flash 5 refuse to be accurate with its sound syncrization???

Flash is more of an animation tool. Director is a video and sound editing tool also created by Macromedia. It is a far superior sound sync’er… I agree.
