Hi, i just installed a modchip on my gamecube (xenogc), i did it myself and trying 5 dvds so far, i burned the dvds on some ridata 4x dvdr and they all work, but I'm getting read erros in zelda TP (its always on the same place, when i try to open a door) and in metal gear solid. So i tried ajusting the laser, and i read that 200~250 is a good value, but when i used the multimeter it was already on 136, then i changed it to 100. The question is.. is 100 too low? will i have problem if i keep this value? Even with 100 the erros on zelda and metal gear still happens, so i think the problem can be the dvd and not the laser. What do you guys think?
