Booting Panzar Dragoon Swapping

[thenix]

I have the 2nd type of saturn and I have modded it so I can swap disks. I get the game to boot into the first movie but when the movies end the game crashes and goes into the bios and says the game disk isn't right. After reading a few topics about this I have also tried adjusting the orange lazer screw to no success. Has anyone else had the same problem, does anyone have any other suggestions?
