Homebrew won't read sd card Apps

Hello, I use and 4 Gb Sd Card to install homebrew and bootmii on my wii, then I formatted this same sd card and create a folder named apps, copy homebrew_browser and other apps on this folder, and when i start homebrew channel the apps don't appear. If I copy this folders to a Pen drive the apps appear normaly.
Someone knows what i am doing wrong on my Sd Card? I trying to install a IOS and it not installing from Pen Drive. :dos:

Thanks!

Sorry if I'm insulting you, but have you made sure that you have the correct source selected?
Press 1 to go to Settings and make sure the SD card is selected.
