PS2 component video cable problem

[scotchnrocks]

I got an HD tv this weekend and a set of component video cables for my PS2. So I hooked everything up and when I go to the PS2 setup menu and switch to RGB cables the screen starts distorting and changing colors. When I move back to standard cables on the menu it works fine even though it's running through component cables.

Is there something else I need to do for the PS2 to properly recognize the component cables?
