Charlie_ps2 had a similar problem with a magic 2 install.
It's on his post here

A clone of an earlier Magic 2 version. 5% deducted for the AR2/GS2 backup isse; 5% deducted for the need to put a 1uF polarised 35 volt capacitor on to play DVD movies properly.
Speak to your installer and refer him to this. if everything else is working fine chances are it's the same problem as above.
If your dvd based games and dvdr's especially run ok then your laser is fine.
If your installer doesn't know then possibly Private message Charlie_ps2 and explain the situation. I don't know if he would but he might be able to install it for you, or point you in the right direction.
Hope this helps,
James
