This is a very strange problem. A week ago, I was using ImgBurn to burn DVDs, and everything was working fine. But then a few days ago, I decided to install CDBurnerXP (while still keeping ImgBurn on the system), and now things are messed up.
Both ImgBurn and CDBurnerXP are able to burn DVDs successfully right now, because I can take those discs and put them into a different computer, and the discs are recognized fine. But when I put the discs into the same computer that burned them, and I try to click on the drive in Windows Explorer, I get a "E:\ is not accessible. Access is denied" error.
So the drive still burns OK, but Windows won't recognize the discs. In fact, if I put any DVD into the drive, including a DVD movie I bought from the store, Windows won't recognize it. Things were working fine before I installed CDBurnerXP, so I think CDBurnerXP messed something up on the system.
I have tried uninstalling the DVD burner in the Device Manager, rebooting, and Windows reinstalls the driver, but Windows still doesn't recognize any DVDs I put in the drive. Any idea what might be wrong?
