Checking for region code compatibility
For a DVD player and DVD disc to be compatible, their region code numbers must match.
These numbers are allocated according to where the player and disc are sold. The 3•2•1
Series II DVD home entertainment systems have a region code which must also match the
DVD discs.
Check the region code number on the carton of the 3•2•1 Series II DVD home entertainment
system or on the bottom of the media center that comes in the carton. Then be sure to
choose only DVD discs that show the same region number on the disc label or front cover.
For example, a Region 1 DVD disc should display the following mark:
Glossary of terms
Aspect Ratio – The shape of the rectangular picture in a TV set. It is the width of the picture
relative to the height. Our standard TV picture, in terminology used by that industry, is 4 units

TV aspect ratios, 4:3 and 16:9.
Chapter – In DVD-Video, a division of a title. Technically called a part of title (PTT).
Component Video – A video signal split into three parts: luminance and two color signals

within the video.
