Hey guys, I have a Acer Aspire X1700 that came with Windows Vista installed. I upgraded to Windows 7 and now my dvd drive doesn't recognize dvds (ie movies, dvd games 'Starcraft 2'). I can play CD just fine. My desktop came with Optiarc DVD RW AD-7203S SCSI. I've tried uninstalling the device from the device manager and rebooting, but the issue remains. I've also read though other threads and have tried their suggestions, but nothing works so far (removing the UpperFilter and LowerFilter from the registry was one that I've tried). This issue didn't instantly occur after the upgrade. Any help would be greatly appreciated.
