Well, I started all over again, but with fewer components now, and finally I could make it My CD now has: - Windows XP SP2 - .NET 2.0 - Symantec Client Security - WMP11 - Critical Updates only, not all the updates, as before (my first post is not correct ) I used nLite again to integrate the updates and WinISO to make the ISO, which now is 725Mb I'll try to overburn it, I think it's possible. If not, I'll just remove WMP11, which will turn the ISO to 694Mb I have to use normal CD-Rs due to hardware limitations here Thanks all for the help!
