how to burn ps2 games for a ps2 with s-box

[tanko]

Hello, I have downloaded several games like ready to rumble 2, batman or tony hawk 3 ( I have the bin file ).I change it with bin2iso to burn it with nero but these game don't work with my modchip ( sbox ) and dvd regionx. I have a PS2 pal 30004.

What is my problem ? Do I need patches ? Is it a problem with nero ?
What should I do exactly with the modchip ( right position always )?

Thank You
