text: There sometimes is a list of DVDs that will work with your burner in the operator's manual.\n\nTDK is supposed to be the best, followed by Sony.  I've been using Imation without any problems.\n\nIf your burner only works with DVR+R, then DVD-R may not work.  Some will burn both formats, but it should say that it does.  You may need to return those DVD-Rs.
