If the ISO is OK, as you've just proven to us, then there are two other
culprits:
1> The CD is not burning correctly.
I think this is not the likely culprit, so try #2 first.
2> You have a CD-Reader device or IDE controller which is not quite 100%
good with DMA mode.
Try running the install with the option to turn off DMA. There's plenty
of posts on this mailing list about that - check the archives to be
sure. I think it's something like cdnodma or ide=nodma or something like
that.

Ed.
