Yes, it can be frustrating if you don't know the process, but this is a very powerful feature of Tourweaver and one that opposition programs would love to have.
As you build a tour Tourweaver makes a "default" movie track called "slideshow". You can view this movie track by clicking on the MovieREC button the Tourweaver GUI.
Once in this view you can make a "copy" of the "slideshow" movie track and modify it to suit your needs. It is possible there to set any of "your" movie tracks as the new "default". You can also set a button (or multiple buttons) to follow and play any of your movie tracks by assigning them.
With movie tracks you can adjust rotation time, direction, set FOV, audio, zoom in/out at locations by adding new "frames" and assigning properties to them.
It is worth reading the (F1) Tourweaver help files (Look for "Movie REC Panel"). But, nothing is going to teach you more than trail and error.
