Back in February, I purchased an LG WH-16NS40 SVC NS50 with firmware version 1.03. I then flashed it to version 1.00. It has inconsistant read issues with UHD Blu-rays. Some rip successfully. Some get stuck in the middle of rips. I am thinking about trying the various compatible firmwares. What are the differences including whether there's a limit on ripping speed, disk/format compatibility, UHD friendly, and official UHD between the ASUS BW-16D1HT, ASUS BW-16D1HU, ASUS BW16-D1X-U, LG BE16NS50, LG BH16NS40, LG BH16NS50, LG BH16NS55, LG BH16NS58, LG BH16NS60, LG WH16NS40, LG WH16NS50, LG WH16NS55, LG WH16NS58, and LG WH16NS60?
