I've got AnyDVD HD, and a 4k Friendly LG Blu-Ray drive with the old friendly firmware. I kinda sorta got a 4k blu-ray to play with Leawo player, but the playback was not smooth, totally unacceptable. B ut it **DID** play the 4-K disc. So I know my drive is OK. VLC wil play regular 1080p blu-rays just fine on my system- but I get an error from VLC when I try to play a 4K blu-ray... I am now ripping a 4K blu-ray disc to an .ISO file, that seems to be working fine, so again it seems my LG blu-ray drive is "friendly enough" and AnyDVD HD has decrypted the disc OK. Now if only I could get VLC to play the discs! I am guessing I need to add some library or something. Any help would be appreciated.
