i've had this issues a couple of times in the last year, the first issue was related to my AMD RX card driver, this was eventually fixed but it took month. I still get this issue using DIRECT3D as the LAV decoder, if you are using this switch to COPY-BACK


edit: I also had this when one of my disks was on its way out, I only new it was on its way out though as stuff i'd copied to it recently exibited this issue but older stuff played fine, anything I copied to the disk from then on had problem. I replaced the disk and all the old stuff was still fine but all the newer stuff was still corrupt. I had to re-rip all the new stuff but it plays fine now.

I was getting no disk errors either so I suspect the controller on the disk was going but the physically partition was going.
