Has anyone made a movie using stitcher?  I would like to see one.  There are no instructions in Help so I don't understand the concept of how to make one or what you would use it for.

There's full info in the user manual. It's included in the box and also in the install as a PDF file.
 
The concept is you position the project at a suitable start point, make a keyframe then move to a different view and/or zoom and make another keyframe. repeat as desired then save the result as a movie.
 
You can play this back as a demo when you don't want someone to take control of the image, such as running demos in display booths etc.

Hi John!
 
To add to what Andrew said above...
 
When you create linear movies you also get the opportunity to offer your clients (assuming you are a pro) multi-purpose collateral material. Linear movies (or still images) derived from your QTVRs offer yet another venue for your clients to maximize their PR dollar (and your bank account). Linear movies are much easier to edit with regards to transitions and format (such as DVD output for TV) compared to QTVR, and can only enhance the value of your QTVR offerings vis-a-vis this multipurpose output scenario.
 
Here's an example of a linear movie derived from several QTVR nodes with a few video additions:

This demo is about more than just creating video. Video can of course be shot with a video camera. But what video cannot do, unlike a QTVR video render, is to recreate a new camera pan/tilt of a given scene once the video is shot. Nor can you easily change lighting and content in a video as easily as you can a QTVR video render; QTVR (in equirectangular format, or cubic) is easily editable in this regard.
 
The QTVR and video formats each offer unique qualities - but in combination provide even more opportunities for creative expression.
