Back in February, my LG BE16NU50 quit reading 1080p and 4K/UHD BDs. I couldn't find another one. So I replaced it with an LG WH16NS40 SVC code NS50, ROM 1.03. I flashed it to 1.02. It has intermittent 4K/UHD BD read issues. It reads my 4K/UHD editions of "2001: A Space Odyssey" and "Terminator 2" without a problem, just as well as my former BE16NU50. I purchased and returned 4K/UHD editions of "The Shining" and "The Last Jedi." After a few replacements, my new WH16NS40 finally read them. If this isn't confusing enough, I had no problem reading "Terminator Genesis" on my BE16NU50, but when I tried to load it in my new WH16NS40 a few days ago, it struggled. So as long as my new WH16NS40 is still under warranty, I told LG that my new WH16NS40 is having 4K/UHD BD read issues my BE16NU50 wasn't having. They told me it's a different drive and that it's software related. I tried crossflashing to various makes and models, such as the ASUS BW-16D1HT, ASUS BW-16D1HU, LG BH16NS40, LG BH16NS50, LG BH16NS55, LG BH16NS58, LG WH16NS40, LG WH16NS50, LG WH16NS55, and LG WH16NS58. I achieved similar results. When I crossflashed to the LG BH16NS60 and LG WH16NS60, my drive actually sounded like it was loading properly, but ANYDVDHD gave me a processing error because these last two firmwares are UHD official instead of UHD friendly. I would like to stick with ANYDVDHD so I can use the software I'm familiar with and just have decryption running in the background. What should I do next? Should I stick with ANYDVDHD and purchase either an ASUS BW-16D1HT, ASUS BW-16D1HU, ASUS BW-16D1X-U, LG BH16NS40, or try another LG WH16NS40? Or should I quit using ANYDVDHD, switch to MakeMKV, and either crossflash my drive to the LG WH16NS60 or purchase an LG WH16NS60? Although if Redfox can figure out how to get ANYDVDHD to work with UHD official drives, I could either crossflash my LG WH16NS40 to the LG WH16NS60, purchase a new LG WH16NS60, or best of all, use my Pioneer BDR-212UBK. Unlike my previous posts, I won't be posting this one in the MakeMKV forum because while that may be the home of the experts of these drives and firmwares for them, those same experts are also the developers of MakeMKV. So I have no doubt what their answer would be.
