Recently I havent been able to run a dvd or cd from my computer by just putting it in. when i put in a disc, nothing happens. I then went into My computer and tried the open the disc but it tells me to insert a disc into the drive. The only way i can get a disc to open and run is to open up my dvdripping software (RipIt4Me). When i start the program i can open the disc and run it. anybody know how to fix this?
