I recently upgraded my old Pioneer 112D burner with 116D (fw 1.09). The problem is that the burning speed has fallen from about 10 minutes to 16 minutes per DVD at same burning speed. I have tried switching cables, replacing (using 80 wire), reseting duplicator firmware (using the latest), even tried with another DVD-ROM.
I have also contacted Acard but I doubt they’ll update the duplicator firmware since 2022D is probably discounted (latest update in 2006).
Is there anything else I can try? I’ve been thining in trying another firmware on 116D. What are my options? What about hex editing the duplicator firmware?
