I just installed a DMS3 in my V4 PS2. It was my second attempt at an install and this time everything seems to have worked fine. The only thing is, when I put in an audio CD, it skips and freezes/repeats a lot. If I put the DMS in sleep mode, the audio CD plays fine. I upgraded to firmware 1.8 before trying a cd. I havent been able to test PSX games, PSX backups, or PS2 backups yet, but PS2 originals work fine when the chip is on and also when it's asleep. Does anyone know what is wrong?
