Alright, check this one out. I have the latest firmware for my Pioneer DVR-108 (1.20), and I have all the most updated versions of my programs, (Alchohol 120%, Nero... etc). But I can't get it to burn 16X on most of my disks. My Verbatim 16X disks work perfectly, but my Dynex and Memorex only burn at 4X. Any Ideas?
