BleepingComputer.com: desktop dvd rw/ cd rw drive will read dvds and cd but will not burn

Hello everyone. my name is Adrian, i recently purchased a gateway gt5228 desktop with the windows 7 upgrade. It all works great but it has one problem, the dvd rw/cd rw drive can read dvds just fine but will not burn. the drive is a lite-on combo sohc-4832k ata device. Windows dvd maker says "a dvd burner was not found. make sure a dvd burner is connected and installed, and then try again". This same program wont even recognize the drive, however other software like nero, recognizes the drive just not that its a recordable drive. I've been researching this problem for awhile now and have found that many people have this problem but have not seen a solution anywhere. Id really appreciate your help so i can get to burning some family home videos. Thank you very much in advance. any i mean any help is greatly appreciated.
