Hi NortsAndOnes, welcome to CDFreaks!
[quote=NortsAndOnes;2034552]Agree with the others here… All TY’s should be burnt at their rated speeds.[/quote] Well, I’d have to disagree then, because in my experience most of the time Taiyo Yuden 16x media (and indeed all 16x media) usually burn better at 8x or 12x than at rated speed.
Taiyo Yuden 8x DVD media usually burns better at 8x or 6x depending on the drive.
There are exceptions to this, but all things considered, 8x is usually the best choice for TY 8x/16x DVD media and 12x is usually a safe choice for 16x TY media.
Good batches of TY media will burn at the highest supported speeds in most modern drives, but quality control is not what it used to be with blank DVD media, and the mediocre-to-bad batches may not like to be burned at the higher speeds.
