I use to have a sony dual layer dvd burner, but it ended up dying on me. My comp already had a "dvd burner" that Nero would never pick up, TssTCorp CD/DVDW TS-H552L. and now the new one i put in from a computer my friend gave me (his motherboard fried and didnt need it) says the same thing except TS-H652D. if they are both dvd writers why doesnt nero pick them up so i can burn dvds!? PLEASE HELP!! It would be greatly appreciated (they are both factory installed dvd burners) or worst case scenarios, are they not dvd burners at all??
