I have a 6 mb flash video that I need to put as an intro. How do I go about streaming this video so the user does not have to sit and wait (which they wont) for it to completely download?
True streaming requires Flash Media Server. (you can get a limited version free from Adobe)
You can create a progressive FLV in actionscript by setting the netConnection to null, but this option is less flexible and less efficient than a streaming netConnection. http://www.adobe.com/devnet/flash/articles/video_guide.html
