I recently installed a Pioneer DVR-109 in my G4. I used up the last few 8X disks that I had and purchased a spindle of 16X disks. It seems to me that it takes the same amount of time to burn at 8X that it does to burn at 16X. Am I missing something? Just FYI, I am using Dragon Burn. It recognizes the disks as 16X and it says it is burning at 16X. Thanks, Kevin
