I've been an occasional user of Movie Studio for many years, and I've recently been using the Platinum version.  My daughter is away at college and needs to do some simple editing so I suggested that she purchase and download the non-Platinum version.  It seems to me that being able to ungroup the audio and video tracks is about as basic as it gets, but we can't figure out how to do it.  In Platinum it's a piece of cake, but the non-Platinum version doesn't work the same way.  Any assistance would be much appreciated.
