Problem Can’t play certain DVD videos
1
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.
1
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.
Note:
Not all DVD drives support DMA well. For more information, see the documentation
that came with your DVD drive.
