## What should I do if I cannot play a disc, or dropped frames and/or sound interruptions occur during playback? (Optical disc drive equipped models)

- Exit all running software other than playback software.

- Try using other playback software, such as DVD playback software.

- Change your current desktop theme to Windows 7 Basic from Control Panel if you have enabled Aero Themes for the desktop theme.

- To play DVD media with Content Protection for Recordable Media (CPRM), you need to install a CPRM pack for playback software on your VAIO computer.

- To play copyright protected Blu-ray Disc media continually, you need to update the AACS key.

  Follow a message displayed on the computer screen to update the AACS key. You can update it through the Internet.

- Uninstall playback or writing software installed on your VAIO computer after purchase.

  For instructions on how to uninstall the software, refer to the help file included with the software or Windows Help and Support.
