I am wanting to insert 4:3 footage (640x480) into a widescreen project (768x480).  The import works perfectly, but it leaves a vertical band on each side of the video.  I want to move the video to the left hand edge and use the empty space on the right for text graphics.  But the bad thing is that I can move the video around, but it never goes all the way to the side.  It crops behind the black bars.  I can off "maintain aspect ratio" and it will fill the screen, but it also distorts the original video.  
The way I created the project was by opening a new document and setting the movie size to 768-480.
Any ideas.
