I need help with my DVD-R/CD-R Writer

Hello,
Thanks in advance for any answers, i need help with my DVD-R/ CD-R Writer drive, it seems as if the drive works perfectly, it reads and writes blank dvd's / dvd-r's, and it can even read a cd, but it wont detect a blank cd-r, this is what happens when i put a blank CD-R in the drive: It act likes its burning!!! Or at least its starting the process, and i think windows media player has something to do with it, just for the fact that it gets busy every time i put a blank cd-r in.
Please can someone help me!? i havent been able to fix this problem for weeks now....... Thankyou
