Depending on system environment, you may find sound interruptions and/or dropped frames during DVD/BD/AVCHD playback. In addition, some discs may not be able to play on your VAIO computer.

When you are playing discs:

• The CPU load increases. Close all running apps other than the playback app you are currently using to enjoy smoother playback.

• Do not switch the display output between the computer screen and an external display.

Some CD players may not be able to play audio CDs created with CD-R or CD-RW media.

Some DVD players may not be able to play DVDs created with DVD+R DL, DVD-R DL, DVD+R, DVD+RW, DVD-R, DVD-RW, or DVD-RAM media.

Blu-ray Disc recorders that support only BD-RE Ver.1.0 cannot play BD-R or BD-RE media created with your VAIO computer. (Blu-ray Disc Drive with DVD SuperMulti equipped models)

Do not plug or unplug cables, such as the AC adapter or the power cord while the optical disc drive is writing data to a disc.

The writing process may take longer to complete than theoretically predicted because some apps write and verify data simultaneously.

Sony assumes no liability for any loss or damage of any kind arising out of writing failure.
