Philips dvdrw885 and ritek dvd+r dl: error

#1

I get and ‘power calibration error’ when i try to write a disc with dvd decryptor onto a ridata (identified as RITEK D01 001) dual layer disc. The red burning led comes on, but after a few seconds it stops and gives me this error. Using w2k sp4, decryptor 3.5.1.0 and nero 6.3.1.25 (gives the same error). After the error nero still reports the disc as empty, so i hope i don’t have destroyed 2 discs…
Does this sound like an error which will be resolved with a new firmware (using the latest 1.7 at the moment), or can i throw away my very expensive DL discs?
