Problem burning and booting ps2 games

[ZELDA70]

Hi . I have a sbox (usb switch) mod and I have to try to boot 2-3-4 times any game I download and burn by myself before it loads. The backup cds I bought with the console (already modded) and the one my friends burn work fine. Do I do anything wrong with cdrwin? should I burn in raw(2352) mode? With my old burner (yamaha 4x) I could burn the game from binfile to a rewritable, then do the image with clonecd and then burn it again on a cd with the same program, and they worked fine! Maybe cdclone settings where correct and cdrwin aren't.
I hope somebody can help me
