HELP!!!

I have downloaded the three ISO files onto my PC then transferred them
to my G4 over my network. Using Toast I burned the first two discs no
probs but Toast will not mount disc three as it says it cannot read
the file type??

Is there any other way to burn this image or any list of what packages
are actually on disc three as I may not need anything from this disc.

Many thanks in advance for all suggestions.
