Im using a pioneer dvr k16 burner. im using 16x verbatim dvd+r (mcc 004) alcohol 120% to rip/burn have booktype set to dvd rom. i have read all the stickies in this thread. i noticed something peculiar in the burning process. I set the write speed to 8x. however during the first part of the burn it writes at 2.4 x then a few minutes later it goes to 4x then 6x then sometimes at the end it will get close to 8x. any help would be greatly appreciated!!
