Just wanting everyone to be informed. The R526S0C and the R526S0D firmware have serious trouble with recording to two drives simultaniously. I have two 48246S drives on the same channel, running with nero 220.127.116.11. Using the "C" or "D" firmware revisions, they will sometimes go to the orange light and never go back to the red one. I can do the same burns with the same configuration on the "A" revision of the firmware, and have no troble at all. Just reply if you want any more information.
