BD+ errors

[ravas]

So I'm using libmmbd to decrypt my blurays for vlc and one of the first BD+ disks I've tried, Independence Day, I've been experiencing a lot of artifacting, unsynced audio, random buffers, and I do have some vlc errors from the terminal for reference, I'm just trying to identify exactly what they mean and whether it's the fault of the disk, the bluray player, makemkv, or some other potential point of failure.

All errors that I've seen in the terminal logs are basically just variations of these 4.

[h264 @ 0x...] left block unavailable for requested intra4x4 mode -1
[h264 @ 0x...] error while decoding MB 0 43, bytestream 53349
