i try sd card 8go class 6, sd card 4go class 4, sd card 256 mo, and no one work
no menu when i use folders, only the led blink like this : oooo-----oooo-----oooo-----oooo, four times, nothing, four times, nothing, continuously.
pressing the reset key has no effect.
But when i put the progams into the root of the sd card it work perfectly.
[Edit] SOLVED
To display all the folders, I have to put a single program at the root of the sd card
in addition to all the folders, so it works.
Thanks for your help.
