Error Installing Package


I currently have vector linux installed and I'm trying to install centos 6.3 on my laptop from my hard drive because my cd/dvd rom can't read dvds but reads cds. I'm using the CentOS-6.3-i386-netinstall.iso to start the installation. I have both CentOS-6.3-i386-bin-DVD1.iso and CentOS-6.3-i386-bin-DVD2.iso on /dev/sda2 and checked their md5sum and they match. After I choose the packages I want to install and click next to start the installation, I get the following error:

A fatal error occurred when installing the ca-certifcate package. This could indicate errors when reading the installation media. Installation cannot continue.

Installing ca-certificates-2010.63-3.el6_1.5.noarch (1 MB)
The Mozilla CA root certificate bundle

I tried several times adding/removing packages but I still get the same message.

When I tried to check the md5sum of the CentOS-6.3-i386-netinstall.iso cd using the following command:

md5sum /dev/cdrom

I got this message:

md5sum: /dev/cdrom: Input/output error

What can I do to fix the problem?

Thanks in advance,

maybe try downloading and burning a Centos cd? I think an iso has to be "unpacked" before it can be used directly, if you are using it on an active system that might cause problems in its self.
