We found that performance differs between devices, but only slightly; the exception is dual-layer writing, where speeds still vary a great deal. The real distinction is in how the burners recognize 16x media; the results here are rather astonishing!" TARGET="_top"><B>10 DVD Burners: </B> 16x and Dual-Layer - or Nothing!</A><br>
