CentOS - Jul 2011 - CentOS 6 DVD install "Unable to read group information from repositories"

Tried my first CentOS 6 install on a system currently running 5.6.  My
attempt was not an upgrade, but a full re-format.  I have verified the
checksums of the ISO and did the pre-install disk verify and everything
checked out.  However after the screen for setting up the bootloader I get
the following error

"Unable to read group information from repositories.  This is a problem
with
the generation of your install tree"

With my only options being "Exit Install" and "Retry", but
of course "Retry"
continues to fail with the same message.

Basically I chose the first option in the menu for the DVD, install /
upgrade, went through all the settings, did a custom layout for
partitioning.  I basically told the installer to re-format my ext3
partitions to ext4 and set the mount points for / , /boot and swap.  Then
after selecting "Next" from the bootloader configuration is when I get
the
above error.

Thanks

1. Was this i386 or x86_64?
2. Have you run Media test od DVD('s) in system in question? Maybe DVD 
drive can not read them right. Especially if you used higher speed to 
burn the disk. I would recommend slow burning like 4x when you burn OS 
DVD's (and 16x for CD's).

And have you by any chance tried the same DVD('s) on any other system?

Use ctrl-alt-F4 to switch to VT4 and view the console messages.  See if the
DVD drive is having problems.
