I'm confused, it happens more often as I get older. Without revealing the magic that happens behind the curtain, wouldn't it be simpler to list which disks the Red Fox Team has made AnyDVD for UHD work with than to try and maintain an obviously very difficult , and ever changing list of those disks it doesn't work with? I don't pretend to understand the steps Red Fox has to go through to get a new release compatible for us to be able to back it up. If it's a task for every new disk that is released, Bravo, you're superhuman! If it is a new process for groups of disks, wow you must be forced to reinvent the new wheel daily, again Bravo. If it is the former, wouldn't it be more expedient, for UHD's, just to release a list of specific disk versions of the movie titles as you release upgrades to AnyDVD, an addendum text file? I can't watch the UHD's I buy until I decrypt them and make an MKV. My HTC doesn't jump thru all the KabyLake hoops. But the movies play just fine once AnyDVD and Clone BD do their magic. I appreciate what you do, and I hope this post isn't out of line.
