crazymf77, If you wish to live up to your nic you'll use the wrong firmware - If you were an intellegentmf77 you would use the correct firmware - If you want to burn Dual-layered DVD's I suggest that you purchase a Dual-layered burner, they're under $100.00 (USD) I hope you'll read enough to see that you'll need a Dual-layered disc to do it - Their cost is down to about $12.99 (USD) each. Ciao, Pete
