My computer won't recognise my dvd burners as burners. it says they are just dvd-ram drives (and sometimes only cd-rom) tht are capable of reading but not writing. Nero can burn with the drives but when i tried putting a cd i burned with it into a cd player, it didnt work. Zune software and Windows Media player also both tell me to connect a burner and restart the software when i click the burn tabs. I have two dvd burners connected.
