i've used disks that say they are only good up to 8x to 12x speed in my 16x plextor, they all work fine, no problems yet.
but i could be wrong, it might matter.
It does matter...
Though some brands do not mention the maximum speed of their CDs right from the start. I spoke to a sales manager a while back (at the time when 12 speed was top of the line) and he said to me that thier CDs were certified for 12 speed, but they did not mention this on the CDs yet, for 12 speed was hardly available at that time. This way they only have to make new jewel case inserts, do a price up of the CDs and they have yet a new line of CDs. (they do not say you can't use their CDs at higher speeds, but if you do it is at your own risk and the manufacturer is not liable for any damage until they say it is certified. It is all about the money and legal stuff, they want their a$$e$ covered )
But when you try to burn at 16 speed (or 12 speed for that matter) on a CD that is only certified for 4 speed, you are very likely to get writing errors, especially with cheaper CDs.
