Verbatim hasn't stopped producing 8x DVD media completely.
Verbatim Europe has recently announced the availability of 8x DVD-R (MCC 02RG20) media with ScratchGuard protection a.k.a. Hard Coat Protection.
This media is of course considerably more expensive than plain non-printable DVD-R media, but if you somehow need 8x DVD-R and you don't mind paying a premium for the scratch protection, then this might be a choÃce for you.
I have seen one on-line retailer in Germany already carrying this media in stock.
