Well, there's several issues possible.  First, make sure you are using
name-brand 700MB (80 minute) CD-R media.  The "cheap stuff" won't cut
it.  Second, try not using "-dao" mode.  Third, try slowing down the
burn speed (try using 1/2 the rated speed of your drive..for a 48x
drive, try "speed=24" or even less).

All of the ISO images must be on that partition and they must be named
EXACTLY the same as they were when downloaded (same capitalization and
everything).
