Okay, I just talked with my contact at Ritek USA and this is what he said:
"Yes, the 8x DVD-R and 8x DVD+R media exists, but we do not have it ready yet. And we don't have it here. They do have the 8x DVD-R and 8x DVD+R media in Taiwan, but it has not yet finished the testing stages. You can expect this media to be available closer to the end of the year. Don't worry, as soon as this happens I will let you know!"
So there you have it, straight from Ritek USA. I have no idea where
www.blankmedia.ca got their information, but they must have things a little confused!
Sorry if I got people's hopes up
edit: I just talked with
www.blankmedia.ca, and they say that Ritek Taiwan is now allowing sample orders, with larger orders to be filled shortly after. Since I don't have a contact in the Taiwan office, I can't personally confirm this.
