we just got a pack of TDK DVD+R 1-16x SPEED|4.7GB discs and when i put it in my tray the computer tries to read it as it always does so i think ok nothing is wrong so far but i later notice that i dont get a pop up with a bunch of icons saying burn to this disc and all that stuff. so i try to burn an iso and it keeps telling me no cd found and that kind of thing. i go to my computer and the disc is listed in there as blank which ofcourse it would be because we just purchased them all. so how come it shows the cd in my computer but will not burn to it ? i have tried with multiple DVD's and still no go. i have a sony DVD burner or so it says on it also says disc+.
