I am having trouble loading some backed up gc games..

I have softmodded my wii, installed the nessecary cmios, have the latest neogamma, am using the right DVD-R's but only about 50% of the games I have tried have worked.... I think I went wrong somewhere in the modding process, cuz they should work.. I have a detailed report of my Wii using syscheck <sysCheck.csv download - 2shared>

Can anyone tell me where I went wrong? Any help would be greatly appreciated. Thank you.
