Burning problems



After using DVD shrink, when it comes to burning a blank DVD-R, nero tells me wrong media is in drive it has been working fine for 9 months. When u go into my computer it lists e drive as dvd rw but when you put a blank dvd in it changes to cd rom. I have gone back to factory settings, this doesn’t help I have changed the dvd writer the times to different makes anyone got any ideas :confused:
