Typical of Pioneer. It’s not new that Japanese drive companies care only about Japanese media while Taiwanese drive companies care about both Japanese and Taiwanese media. BenQ and Lite-On have always supported the most types of CD and DVD media. A similar but worse example is LG and Samsung of South Korea don’t test some media if they can’t find them inside South Korea (talked to both myself.) Philips moved their optical business to Taiwan right next to where BenQ is for such reasons and LG and Samsung spend much time in central Tokyo to develop their drives because that’s where all the development and licensing happen.
Regardless of that, Pioneer 110 seems to do well. Any rumor of DVR-A11/-111?
