Hello, I had downloaded the dvd image for Fedora Core 5 (FC-5-i386-DVD.iso) from fedora site. sha1sum on the image gave results according to what should be. I am able to mount the DVD and read it contents. I am burning it with: growisofs -dvd-compat -Z /dev/dvd=FC-5-i386-DVD.iso when booting it I get: "isolinux: Image checksum error, sorry" boot fauled: press a key to retry. any ideas? IB
