Is this the issue with all the DVD's or any particular DVD?
IN which player are you trying to play the DVD?
Your DVD decoder and Windows Media Player have copy protection software that decodes the information on the DVD just before displaying it. If this software doesn't start correctly, you might receive this error. Remove the DVD from the DVD drive
and then reinsert it. This will force the copy protection software to reset.
While the DVD is out of the drive, make sure that your DVD is clean. If your DVD is scratched or dirty, the DVD drive may not be able to read it correctly, and you might receive this error.
If this doesn't work, try the following:
If you have been able to play DVDs on your computer before, and you receive this error message, you might be able to solve the problem by restarting Windows Media Player or your computer.
If you receive this error message the first time you try to play a DVD, you might not have a DVD decoder installed, or your decoder software might need to be updated. In addition to your DVD-ROM drive and Player software, you must have either
a software or hardware decoder to play DVDs. Hardware decoders and their drivers are available from third-party manufacturers. For more information about software decoders. If you have an older decoder installed, contact the manufacturer of the decoder to
obtain an updated version that is compatible with Windows Media Player.
