I just purchsed this benq drive last week and I haven tried everything I can think of to try and get a good burn. I have tried -r and +r media / G7Z9 and G7P9 firmware along with B7T9 firmware. Can someone please help me and tell me what I am doing wrong. I have attached a copy of a quality scan of the best disc I have burned so far. All of the discs I have burned are peeking at the end and most are failing.
