VAIO Computer Quick Start
What software do I use for CD-R/CD-RW software functions?
Sony recommends using the preinstalled SonicStage software and Windows®
XP to create CDs on your VAIO® computer, if the specific model you purchased
is preconfigured with all of the necessary components for CD-R and CD-RW
capability.
Downloading the optional RealJukebox CD-burning component to create CDs on
your computer may interfere with normal system operations.
Why can't I use the DVgate software?
If your computer is using the Ultimate Battery Life profile as a power saving
mode, you cannot use DVgate™ software. Please select another profile.
Preferably, connect your computer to AC power when using these features.
