We nee to some more details. You have been on the form of high and know the rules. You are supposed to give some detail in the first post.
We need to have some idea of what kind of computer you are using. We see it you are using Windows 7, is this the actual release of Windows 7 or was it a beta version?
Also what about your DVD drive? Is this the standard drive that came with your computer? Is it an external drive?
What other software do you have that would access the DVD drive?
