If you want to load a new Sparks plug-in but all the Sparks buttons are already in use, you can replace an existing Sparks plug-in with the new one.

To replace an existing Sparks plug-in with a new one:

1. From the A/V Tools box, select and enable Sparks.
2. Press Alt and click the existing Sparks button in the Sparks menu.

   The file browser appears.

3. Navigate to /usr/discreet/sparks or /usr/discreet/<product home>/sparks and select a Sparks plug-in.

   You are returned to the Sparks menu, and the name of the new Sparks plug-in appears on the selected button.
