Ok i know the majority of reviews on here look bad BUT.
In order to burn data to these discs you have to understand how they are manufactured, conventional dual layer dvd's (verbs and ridisc etc), the big brands, use a more expensive way or manufacturing, where the layers are created already together, these are created using 2 separate layers and then those are stuck together. it is because of this that some burners wont like burning files to these DVD's.
i have burnt varying types of media and files over the 25 provided. i will say this once
NONE HAVE FAILED AT 8x
they are designed to be burnt at 8 speed. if you are trying to burn at 2.4 or 4 etc. your success rate will not get any better. i have already explained the manufacturing process in the simplest possible way and i hope readers can understand what i am trying to say.
these discs are as good as any other dual layer media, and i believe that these reviews do not do them justice.
