could anyone suggest what I should do with my 451S with latest official firmware to make it produce readable DVD+RW and DVD-RW discs? patch it with a hacked firmware as well? I don't need faster speeds, I only need standard speeds and DVD's I can actually read after burning. do the hacked firmwares improve reliability? darn I'm frustrated with my 451S, luckily I only write +/-RW, at least I can return them to the store once I'm fed up with writing on them 30 times in a row without a single success.
