Right ,you've all probably heard this before but here goes ,its a bit different this time. I was burning cdr's happily then one day it just came up the error. I have changed media and up/downgraded NERO tried "burn at once" program and nothing. I even installed my old SCSI Plextor 12432 and the same result so its not the software and not the drive.My original burner was the A105 pioneer and with that i can burn DVD's with no problem at all. Another question also, Does a dvd combo burner have two lasers ,one for cd and one for DVD??
