Cause
A DVD video may not play back because the region setting on your DVD player doesn't
match the region code on the DVD-ROM disc. DVD players and videos use region codes to
prevent the playback of video that was intended only for a certain region or market.

Solution
To get a copy of a DVD video that's compatible with the region code of your DVD player,
contact the vendor of that video.
Problem Can't record DVD video

Cause
The video source may be copy protected. Your Matrox product may not let you make copies
of copy-protected video. (Some video sources let you make a copy of a video, but you may
not be able to make a copy of that copy.)

Solution
To get copies of a copy-protected video, contact the vendor of the video.
