I would like to buy some Ritek DVD+Rs from Newegg but didn't know what speed to buy. I have a Liteon 451 flashed with the latest 'standard' firmware found on this site. Windows XP Pro SP2, 512MB PC133 RAM, 1.6GHz P4. Should I get 8x or will some hacked firmware let me write at 16x? Sorry for the newbie questions.
