I do not think this is isolated to the 64 bit release. Since moving to CentOS I have been able to record the DVD iso's with all manner of DVD recording software on many machines and operating systems. However, unless I use growisofs, disks created with other software will not boot on any of in 10 test machines I have. I do: growisofs -Z /dev/hdc=path_to_iso_file/centos_dvd_iso_file_i_want.iso (hdc is my DVD recorder, yours maybe different) This issue needs to be be looked at in relation to how Redhat build their disk images be that RHEL or Fedora to give CentOS the same quality of disk images.
