Just looked at the main page for the BDR-206MBK Pioneer drive, it says it can read BDXL discs, that's not the same as UHD. As I said in my last post, that drive is from 2011, so I doubt it will be able to read the discs without a firmware update if at all. There have been many drives since then that can also read BDXL, but the only one I've found that can actually see the information on a UHD disc is the LG BH16NS55
