A HEVC clip Sintel_4k_27qp_24fps_1aud_9subs.mkv is showing corrupted playback with MPC but playing fine with PDVD on Nvidia GPU . After debugging I found ucNumDeltaPocsOfRefRpsIdx is not correct for MPC.

Setup I used:
OS : Win7x64
GPU: Nvidia GTX960
graphics driver: 347.23(try any latest available)

Fixed in LAV Filters, thanks for reporting. The fix will show up in MPC-HC the next time @Underground78 updates the built-in filters.
