Both of my optical drives will play cds, games etc. but most of the time when I pop in a dvd, I get a message from Microsoft saying it has encountered a problem and needs to close, and the dvd will not play. The error number is 1000. Any help with this would be greatly appreciated!

Thanks.

Is this something new that has started?

Any changes that either happened or that you perhaps made to your computer around the time that the problem started; particularly any Software or Hardware that you installed or setup.

Can you also post exact error?
