The last batch you’ve bought has the so-called phthalocyanine dye (yellow). I guess you bought DataLife and not DataLifePlus/Super Azo/Sonic Azo/Metal Azo ones? The DataLife Extra Protection Surface are inferior media, not made by Verbatim/Mitsubishi and not with their media code.
You’re mixing up things with dark blue. Verbatim’s own Azo technology (dark blue or light blue) is different from Taiyo Yuden’s Cyanine (greenish or light blue) technology. The most compatible disc undoubtedly is made by TY.
TY is always Cyanine (green-blue).
Verbatim’s own DataLifePlus media is Azo (blue).
Other companies all use Phthalocyanine (yellow).
Nowadays, Cyanine and Azo media do not have the stability issues which plagued it in the past, they are at least on a par with phthalocyanine media, almost no manufacturer bothers to make good phthalocyanine media.
I hope I got it all right, maybe somebody else can make it better though.
