So I received a 100 pack of HQ AZO 4x DVD-R blank discs. I get excited and pop one of them into my ND-1300A burner, which most blank media retail sites say is compatible with my recently purchased HQ AZOs. and burn some vob files to one of them with Nero burning rom. Immediately the event summary says that its an illegal disc. This comes as a surprise to me, as I'd been using fujifilm DVD-Rs with no problem for some time. What could be the problem here? Is it the 4x of AZOs? Is it Nero? Is it my burner? Should I ship them back and get a refund? Any suggestions are appreciated.
