i've got the most recent firmare 1.09 and have had firmwares 1.06 to present. all the same. so, when i first got this burner i tried memorex 16x media. the burner would slow down. you could hear the spinning of the burning process slow down around 75% complete. after burning i always test the DVD to make sure it completed in good shape. 3/4's way in the DVD would always crash pc. not a hard one. just like wmp would crash and freak out pc. like if i burn 4 movies all movies were fine except the 3rd movie 3/4's way thru it. now, if i use 8x memorex everything is sweet. all the time. is there a problem with firmware i'm unaware of? is my burner shit? Ahead Nero Burning ROM v22.214.171.124 Ultra Edition isn't good? pretty retarded buying a $100 16x dvd burner and the fucker can't burn @ 16x! i've also tried slowing the 16x burning down to 12x or even 8x and it doesn't matter. always fucks up. like i said though. 8x media works great! reason i got 16x media this time again was the store didn't have any 8x at the time and i needed some discs to burn at the time. so, i figured i'd give it another shot. bad call. what's the deal? thx.
