Picture and sound slowdown and the picture crumbles into pixels in some DVD images on the same episodes, but if you watch vobs separately from the DVD image, then everything is ok. Other players (eg MPC, GOM, PowerDVD) play without problems.
Please fix this bug in VLC Player.
My config: i7-6700K, Intel HD Graphics 530, 32 gb ram, Windows 10 Pro v20H2.
