My PS2 has a Messiah chip installed. I have never tried playing DVDs in it before I had the chip fitted. When I try to play an original DVD or a DVDR it will not recognise that the disc is there.

I put the disc in. Close the tray and reset the PS2. It spins up and goes to the display for checking the memory card - same as if no disc was inserted. Any ideas anyone?

Thanks,
