Yeah I figured from browsing the forums, it really depends on Burner (firmware to come extent) and media.. Different media behaves differently in different burners.
I opt'ed for the TYG03 media since its x16 and my pioneer/sony drive was released after the dvdhs.com x16 burning standards were ineffect.
Also heard of layer issues with TYG02 some where on the forum. Figured go with modern dye used in TYG03 still in use today.
BTW - I love this forum, always interesting to know about the inner workings of things you take for granted. ie. media/burners. especially different media and error rates.
