How do I burn a PowerPC DVD from my TechTool Pro 5 DVD? (v 5.0.7)

To create a physical bootable DVD from the TechTool Pro 5 DVD disc image you will need a blank DVD-R or DVD-RW disc. The DVD you create will contain Mac OS X 10.5.8 Build 9L35 as its operating system in order to boot PowerPC-based Macs capable of running Mac OS X 10.5.x.
 
To create the DVD:
1. Copy the TechTool Pro 5 DVD (PPC).dmg file from the Extras folder to your desktop.

6. Click the "Burn" icon (located in the upper left corner of the Disk Utility window).
7. Insert a blank DVD into your computer's DVD drive and then click Burn.
8. Once the burning process has finished, your Mac should eject the DVD.
