alright so i put a .mov file into a flash document that will be delivered on a CD but when i play the swf the video and audio of the .mov gradually get out of sync (the video becomes slightly faster than the audio). so i made the audio track and video track seperate but it still does it. why is my video playing slightly faster than the audio?

thanks

Do you have a preloader on your files? So that everything would load before it is even played. I have not worked with sound much so this may not be any help. Good luck figuring things out though.
