My comment was not based on the "media" speed as rated by the 
manufacturer. It is difficult (if not impossible)to find any media rated 
less than 12X today.

I was referring to the actual speed used in burning, and my 24X cd 
burner will only burn at 16X on a cd that is rated at 8X. (I still am 
using up some that I bought almost 2 years ago because they were behind 
ones I had bought since then.)

The cost of the media is really not a factor, the time involved becomes 
the critical one if you are making several copies. True, if you insist 
on using only the best media then its price is a factor, but not if you 
use the readily available quality.

My 2X burner used to take 40 minutes per CD, thus 2 hours to copy 3 CDs. 
And even if you could do it while doing other things (and I did) it 
still involves that much elapsed time. Most of us are too involved in 
other things to dedicate 4 hours to make 2 copies of the distro that we 
plan to sell. Thus the faster burner and ability to make copies quicker 
becomes of great benefit. 5 minutes per disk, 3 disks per set --> 4 
copies per hour.  A major benefit and thus the price (time) per copy 
drops dramatically.

Media cost also has dropped to just under $0.12 per disk for the 16X 
disks as compared to over $1.50 per disk (8X in bulk) as little as 2 
years ago.

on the 2X burner the fixation took 2 minutes.
on my 24X burner (burning an 8X cd at 16X) it takes 21 seconds.
