Thanks for that. However I'm in the UK, unfortunately!
Anyone recommend a reliable UK based supplier that is not likely to be selling T-Y "fakes"? I see a lot of discussion around these disc using T-Y media codes but not really manufactured by them, but it seems sometimes difficult to tell which are genuine (until you get them delivered of course!).
Also, my original question remains.... is using media rated faster than your drive generally dangerous, or is it only the Pioneers mentioned on www.dvdhs.com that need the firmware upgrade to be safe.
My writer (LiteOn Slimtype SOSW 852S) is supposed to write DVD-R at 4X, but I want to know if I can safely buy the more common 8X media.
