Error Code 0x80020025 Upon Disc Insertion

Whenever I insert a blank disc, I get an error message (after the usual dialog box) saying "The disc could not be used because the disc drive is not supported. (Error code 0x80020025)"

How can I fix this problem?

Also, when I inserted a previously burnt DVD Video, as usual DVD Player opened, but when I pressed play, I got an error saying "Supported Disc Not Available."

If it helps, audio CD's play fine (commercial)

-Thanks in advance
