RPC Codes are placed on Movie Discs that correlate to the region they are intended for sale. A DVD Drive must likewise be set to a region. For example, a PC user located in Canada, would have their DVD Drive set to Region One, or a PC user located in France would have their drive set to Region Two. A DVD disc can only play on a DVD drive coded for its region. The Canadian PC user could only play Region One coded Movie DVD discs and a French PC user could only play Region Two coded movie discs. The Regional Playback Control system does not allow users to play DVD discs that are not set for their drive. If a user attempts to play a DVD movie disc for a region the DVD drive is not set, the user will receive an error message explaining the DVD title is of another region and cannot be played. Setting and Changing the Region Setting of the DVD Drive To play a DVD movie, the drive must first be set to a Region. Several methods are available to set the region, which are transparent to the user. · The Manufacturer may set the region at the factory · If no region is set at the factory, most software will set the drive to the region coded on the first movie DVD disc that is played. · If the first disc is a multi-region coded disc, the drive will be set to the region determined by such factors as time zone, or language etc. Once a drive is set to a region, the region can be reset, but for unusual circumstances only, such as when a user relocates to another region. Refer to your movie player software manual for specifics about changing the region. In general, to reset the Region, use a DVD movie disc set to the new region. A notification box will respond, explaining the disc belongs to another region and cannot be played. The notification explains the region setting can be reset. Follow the instructions to reset the Drive. NOTE: High-speed drives spin the disc at a high rotational speed. If a CD has printing on only half of the disc, or if there is a slight imbalance in the CD, the imbalance is greatly magnified by the high speed, causing the drive to vibrate or produce a fan-like noise. These effects are inherent in the high-speed technology and do not indicate a problem with the drive. Emergency Ejection (use only in the case of an emergency) If the disc tray does not open when the OPEN / CLOSE button is pressed: Make sure that the power of the DVD-ROM is turned on.
