Hi, I bought a PS2 today the wild today and it is functioning rather strangely. PS1 games all work. Some PS2 games work but others do not and a message saying "disc read error" or something similar to that come on the screen. Also, dvd's do not seem to work. I have concluded after a lot of game testing with about 20 games that I know work that the discs with the blue bottom work excellently while the silver bottomed discs get the disc read error message. Music CD's work fine. I thought i read somewhere that sometimes there is an adjustment that can be made so that everything will be read properly. Any and all advise and or suggestions are welcome because unless I can fix this easily I have a rather expensive PS1 in the shell of a PS2. Thanks in advance for all of your help.
