I have a Toshibe Satellite laptop with Windows Vista. It no longer reads most Dvds and it makes a weird grinding noise. Its seems like it keeps trying to download them instead of playing thiem. Plus it says its unable to read them as well. Also, sometimes if I turn it off and then turn it on again with a dvd already inserted, it is able then to play the dvd...There are only a few dvd's that it does with this. It is still able to read music cds. I bank my computer around alot. I do not have internet at home so I am woefully behind on updates
