I recently bought a spindle of Ridisc Xtreme Dual Layer dvds and my laptop dvd+-RW drive wont accept it. I have a Sony A317M Laptop with DW-D56A drive with the latest firmware - PFS3. My drive accepts Verbatims and other dual layer discs but not these ones. I burn an image with Imgburn and i get an error message like this: Action: Set layer 0 capacity Sense Error: 5 / 27 / 00 WRITE PROTECTED CDB: SEND DVD STRUCTURE 0xBF 00 00 00 00 00 00 20 00 0C 00 00 I have also tried dvddecrypter, Nero and other dvd burning programs with no luck at all. Does this mean that my dvd drive is not compatible with these Ridisc Xtreme discs?? I dont really want to keep buying verbatims as they are quite expensive. Any ideas??
