I have a rather strange problem with the MGS2 demo disk that came bundled with Zone of the Enders, when I use it in the PS2 it will not load it, the system will keep trying to spin up the disk but will never load the disk, it does not give any errors such as not being able to read the disk. The disk itself is scratch free and is like new. The playstation 2 also works with all of my games (16 currently) both of which are on CDs and DVDs. The MGS2 demo disk will also work in another PS2, which is a newer model - SCPH 30003R. My system model is the one before that the SCPH 30003, they have both got the newest DVD drivers on them (2.10). Anyone know why the demo might not work?, I personally think that as it is an early demo it is just bugged anyone got any other ideas?
