Which program do I use for CD-R/CD-RW functions?
Use the preinstalled Sony SonicStage software and Windows® software 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.
You can also download the RealJukebox CD-burning component to create CDs,
but it may interfere with your computer’s normal system operations.
Why can’t I use the DVgate program?
If your computer is using the Ultimate Battery Life profile as a power saving
mode, you cannot use DVgate™ or Smart Connect software. Please select
another profile. Preferably, connect your computer to AC power when using
these features.
