I have always used tdk dvd-r. Up until now I have only used 2x, on my last trip to the store they only had 4x so I figured no problem. I have found I can still only burn at 2x. I identified the code as ttg01, in omni patcher the firmware doesn’t list it. I figured I would convert over to 811s, which I have but the firmware still doesn’t support it. I have checked the 832s firmware and it does support it, but is there anything I can do until I buy the 832s.
