I have a Sony VAIO VGN-FS660/W and have a problem with the CD/DVD unit. Recently the computer was full of viruses and I had to re-install the OS, it has Win XP Pro. I lost my system restore CD's, so I had to search for a copy of these CD's and got a copy from a friend. Since the re-installation, the problem began: It only reads original CD's. When I load a burnt CD or DVD, it shows a single windows media player file, with a size of 0 bytes, no matter what is the actual content of the CD or DVD. Before the re-installation it read everything fine. Now, for example I have a burnt CD with a copy of some drivers and can't open it because of this issue. What could be the reason of this problem? A mis-installed driver, or a patch for the OS to read burnt CD's?
