RH9 second ISO image problem

["quetzco\ inwind\ it" <quetzco inwind it>]

Hy,

I?m driving crazy with the installation of RH9.
I?ve downloaded the ISO images three times.
I?ve verified the images with MD5SUM and everything was OK.
I?ve built the CDs using Nero 5.5 (700MB CDs)
After the boot from the disk #1, I?ve used the CD verification functionality, and I?m obtaining always the same response:

- the second disk is wrong

Having doubts regarding my CD writer, I?ve used four different writers, but the problem still remains.

Trying to proceed with the installation anyway, it fails when installing XPDF modules from the second image.

Could anyone help me?

Best regards

Antonio Antoniali
