Weird Red Screen prob

[angry_donkey]

hey...hopefully someone can help me.. i copied Discworld 2(NTSC) tonite and when i use my psxchange disc it loads for a bit then i get this red screen witch has a bunch of hexidecimal stuff and along the top it says "Watch in amazement as the playstation eats its self!!!"..any help would be appreciated. oh and the original plays just fine. almost every other game has worked no sweat. The original game also does it when i use the psxchange disc too
