I own a PCG-GRT915M. The problem i am having is with the dvd drive. It is recognising audio and cd/r data discs, but its not recogniseing any form of dvd disc wether it be video or just a dvd/r. When i put a disc in, it dont register in my computer, but still knows its there because i can still go into the dvd drive, but nothing shows. help!!!!
