I have a problem which may be simple to fix:

I have a video on on track 1.
Then add a new video to track 2 - as I do this my video on track 1 is pushed to the right for the duration of the video i added to track 2.

Is there a way to disable this pushing? Ie, when i put a video on track 2 it doesn't move the video on track 1?
