This install gives you options to install an alternative QuickTime .mov file player, as well as installing the QuickTime Movie codecs and a QuickTime DirectShow filter that allows DirectShow players to access all QuickTime formats.

If you already have the QuickTime player installed, with its codecs, you may want to just install the QuickTime DirectShow filter to allow access to these file formats within SAWStudio.

Uncheck all options, except the QuickTime DirectShow Filter in this case. If you do install everything, it will defunct your current QuickTime player and delete all QuickTime codecs upon an un-install. 

When installing the QuicTime.ax DirectShow filter, it sets itself to route all .mov files through it.
If you would like your system to open general QuickTime movies through the QuickTime player, as they do now, but add the feature of allowing SAWStudio's Video Track Viewer access to many of the same .mov files, then you may want to make this change to the registry after the QuickTime.ax filter has been installed.

Goto the Start Menu and Run option... Type Regedit.

Goto:

HKEY_CLASSES_ROOT/Media Type/Extensions/mov

Rename to mov-

Done.
