problems with some xixo.iso xbox

I have problems with some XBOX xixo.iso with xemu emulator on my system.
Enter the Matrix (Europe) (En,Fr,De,Es,It).xiso.iso(Dirty or damaged disk)
Grand Theft Auto - San Andreas (Europe) (En,Fr,De,Es,It).xiso.iso (Please insert a xbox disc)
Grand Theft Auto - San Andreas (Europe) (En,Fr,De,Es,It) (Rev 1).xiso
(Please insert to xbox disc)
Grand Theft Auto - San Andreas (USA) (En,Es) (Rev 1).xiso.iso
(Please insert to xbox disc, but if I change EEPROM to English it works)
Lord of the Rings, The - The Return of the King (Spain).xiso.iso
(nothing, does not load, does not start)

I don't know if it's a problem with my system (with eeprom in Spanish) or some error in the xixo.iso or a corrupt download.
I only have problems with these isos of 100 downloaded isos
Thanks and regards.
