If you did accidently drag the audio or video to make it out of sync,you can do ram previews to get it back in sync, then click on the video event, hold down the cntl key and click the audio event. Then hit the g (Group) key. this locks the two events so if you drag one, the other follows. For the opposite, select both events again and hit the U (Ungroup) and you can then move each seperatly again. Hope this helps, Danny Hays
