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 playing discs:

Close other video related software applications.
Do not switch the display output between the computer screen and an external
display.
Your VAIO computer plays discs with playback software, which causes the CPU load.
Therefore, by closing all running software other than playback software, you can
enjoy more smooth playback.

Notes on playing recorded discs on other players

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.
BD-R or BD-RE media created with your VAIO computer are not playable on a Blu-ray
Disc recorder that supports only BD-RE Ver.1.0. (Blu-ray Disc Drive with DVD
SuperMulti equipped models)

Tips for successful writing

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 software writes and verifies data simultaneously.
Sony assumes no liability for any loss or damage of any kind arising out of writing
failure.
