To piggy back off of Holland's post. If there is a yellow warning mark next it, this is normally a registry fix that can be fixed by changing the lower and upper filters for the drive. If you have this please tell me and when I get off i will see if i still have the registry fix file. This most commonly happens when multiple pieces of software have access to the burning function of the cd-rom. Most common was I-tunes around updates when i would see this in my tech support job.
microsoft has a fix for this on there website http://support.microsoft.com/kb/314060
It seems to be the problem. I have that yellow warning sign you are talking about and tried the link you gave me. But I have Windows 7 and I can't edit the registry myself, I have to run the Windows troubleshooter but that thing can't fix the problem itself... I'm kind of stuck. I get a message telling me that there is a problem with the driver, it reinstalls the driver but that doesn't fix anything at all. It also tells me that "the modifications might not have been detected" (I'm translating all this from the french messages I get so that might not be the exact words though).
IF you could i have the actual registry file. Provide me an email and ill send it with the instructions.
