Hacking Getting DVD read error 559

[El-Grosso]

I've been away from the homebrew business for ages. I think I am now completely updated with version 4.0 on my Wii and the neogamma backup loader. It plays all of my games that I had previously burnt, but I just wrote a 1:1 DVD of madworld, and I keep getting DVD read error 559, while all my other games still work fine. I tried burning another DVD, but the same error. Thanks for the help.
