If the checksums are OK, the odds are that the discs are OK.  The disc
check in the installer often fails.

The most reliable check I've been able to run on Intel and AMD platforms
is to disable DMA ("boot: linux nodma"), do the disc check, then reboot
with DMA enabled to do the actual install (after the disc check says
they're OK).  I don't know if the PPC system allows that (it probably
does), so try it.  Remember, turn off DMA ONLY for the disc check.
Leave it enabled for the actual installation.

But again, if you got no errors on the burn and the ISOs checksum
correctly, your odds are over 97% that the discs are fine.
