Sony Drive Speed Selector
 

Sony has released a speed selector software for their A510 DVD burner called Drive Speed Selector (DSS). It allows you to increase the drive's speed when reading DVDs for both single and dual layer DVD ripping. Using this utility to set the drive to overdrive mode, the drive will read DVD-5 at 12x and DVD-9 at 8x speed. For those who don't want to take the long survey Sony imposes on you, here's the direct link.
