Simple question...URGENT!! please help!

I have a flv that was created in squeeze from a 7 min video clip. When I embedded it in the swf file the audio and the video didn't match up. where the audio was playing fine but the video seemed to be in slow motion. does anyone know why this is?

so now im trying to load the fla dynamically,
I have a empty MC on the main stage with the action script

loadMovie("video1.swf", "video1");
video1._xscale = 100;
video1._yscale = 100;
video1._x = 330;
video1._y = 143;

but it doesn't stream, i cant get it to load the file and play it. I'm not trying to make anything fancy just trying to get the video to play through flash. I dont need controllers or anything(maybe a preloader) but I just can't seem to get this right. I just dont know enough about using movies in flash to get this right please someone help.
