I have modded my PS4 V4 with a messiah, but have a strange problem with it.
when i try to boot a original PS2 DVD Game i get a read disc error and jump to cd-player screen. also get the same problem with ORG. PSX Games.
Burned PSX and PS2 Games boot fine without a problem, tried to short the wires to minimum but no luck.
DVD Movies play without a problem.

any Idea's.
