Adding a new scene stops the action

OK - That was Lateral,

What I mean to say is that I have a two-scene movie with some action scripting that works fine. I add a new scene to the beginning of the movie and insert a movie clip with a .flv file in that scene. This causes the action to stop about 1/2 way through the second scene (which used to be the first scene). I get that the scene I added has, somehow, borrowed time from the following scene but I don't know how this could be or how to fix / defeat / understand this. To make it more interesting, all the scenes play properly when selected, one scene at a time, and if I start on the second scene, it plays normally through to the third scene. I was under the impression that the scenes were independent, running one after another in the order of appearance, with no interference. Bad impression, eh?

If anyone reading this goes "Oh, yeah . . . THAT", please post. I will attempt to start from the beginning to solve this problem for now, but that would be really time consuming if I already had a few scenes created.
