Follow these steps to burn DVDs with DVD Architect:

• Go to "File" > "Make DVD".
• Click the "Burn" button.
• Before the material can be burned to disc, the files required for the burn need to be placed in a special burn folder. Specify where you want the files to be placed by entering a path into the "Burn folder" field. You can also click the "Browse" button to manually select the desired location.

Prepare
The "Prepare" function can significantly reduce the time it takes to process your project if you've only made changes to one part.

• Click the "Prepare" button.
  You should now see a percentage estimate of the unchanged portion of your project. This is the portion which can be reused.
• Click "Next".
• Now, click the "Optimize" button to adjust the size of the project and remove any errors.
• Click "Next". 
• Click "Finish" to start burning your project.

If you want to disable the "Prepare" feature, click "Advanced" and turn the "Smart prepare" setting off.
