hmm ... does it just keep spinning and stopping or what? sounds like u r using crap discs to me that are loose on the spindel. How has it worked in the past and how are the other games working? Usually when u get a problem like that either the disc is at fault or the psx's lazer is on its way out.

Having the trailer at the start shouldn't cause any problems, try copying a straight off copy of the game without cheats and see how that works, it could be that the cheapo discs u r using r causing the problem. You changed to a cheaper brand recently?
