some trouble with installation

[Mattia Forza]

i have some trouble with the installation of FC4 on my iBook...i have  
downloaded the DVD-iso image from the fedore web site...i've burned  
it...made the partition to install FC4 but....it doesn't boot from  
the dvd...i don't know i've had some problem during the download or  
during the burn...i only know that it doesn't work...and i need it to  
work ASAP...

please tell me what to do (working on a macintosh ppc with MacOSX  
10.4.3 installed...i need to use my iBook in dual-boot)
