9.4 gig media compatability (DRU 500 AX)

[sellpipe]

I see these blank DVD R's advertised as 9.4 gig storage. I assume they have recording surfaces on both sides.
I dont see these type discs addressed anywhere on this forum. Are these blanks compatable with most DVD recorders?
To be more specific, Are they compatable on the DRU 500AX?

It is sort of like two DVD-R discs glued together, making a recording surface on both sides. If you can burn Ritek DVD-R then you can burn the double sided Ritek DVD-R (my DRU500A burns them fines, and at 2x with the appropriate firmware upgrade).

For my use, it is kinda pointless to use them, since they cost more than 2 DVD-R's, and you have to flip the disc manually.
