I have a Sony Vaio Laptop with a blu-ray rom drive but when I put a blu-ray movie into the drive it spins for a second and stops, unlike with a DVD or audio disc where the drive starts spinning for a while. The computer says no disc is in and Corel Win DVD/BD won't pick it up either. I did delete a few programs to speed up my computer so i'm wondering if I accidentally deleted something for the BD Drive. The computer still says 'BD ROM Drive'. Anyone have any ideas?
