Problem With PSX games. Please need help

Hi guys i am having some problems with some psx games - i do a copy of them they load well - ie the initial video and menu all load well - but when i come to play the game - it tends to stop on loading - it freezes.

Does anyone have a clue of the reason for that

thanks in advance

PS - i have a plextor w4012A

What games do you back-up (ps1 or ps2 ,whats the name of the games)?With what software?..and so on…

als o did you burn at a rediculously fast speed, its wise with psx to slow down to 4 or 8x.
