Yup, was good stuff to find back when all the Office stores carried brands that could have anything in the spindles. I think I had some that burned at 8x very nicely with my awesome NEC 2500, the first really good DVD burner I got besides maybe the Sony 500 that was my first one. I try to forget the LiteOn 811 though many here had great luck with theirs and Z made them even better, which gave us our start here...
I still have some really old blanks here and there I should dig out and see what they are and maybe do some burns.
