I regularly experience a freeze when I playback a 1080p h264 file. However, audio keeps playing just fine. When the freeze occurs, I am not doing anything other than playing the video. To resume playback, I just stop the video and press play again. Usually no reboot is required.
My setup: connect the Vero 4k to an external DAC with spdif, and my files are on a NAS (mounted NFS share through fstab).
