Where does the install go bad? Usually this indicates where the problem
is. :) One idea: if you have enough HD space on the Mac, copy the CD to
the mac hard drive. Any place on the CD that has a CRC error should
prevent you from copying the file, so it should become apparent which
files you need to DL. If you can't copy any files at all, or access the
CD, then it could mean that the defect is in the TOC on the CD, and will
make it pretty much impossible to do anything.

Of course I have only tried this process on an Intel machine with
RedHat, but.. I don't see why it *shouldn't* work. :)

If this is the case, then I could just d/l that file and burn a new CD with it, rather than wait for snail mail back and forth to TSS for yet another defective CD. (I'm on a dialup, so d/l'ing the whole CD image is not an option, and this is the second defective CD already.)
