Thanks Chris, good point regarding filesystem actually being embedded in the ISO. I was simply browsing the available options in the Roxio MyDVD tool for something I might have set incorrectly, and your point hadn't occurred to me. I did create the DVD by "burning ISO image" (hence you are undoubtedly correct that any MyDVD program options regarding filesystem choice become irrelevant), and indeed the DVD contents as viewed on a Windows machine do show up correctly (I see release notes html files and multiple directories with RPMs etc). But the SLC54 ia64 DVD is just not bootable.

However, there is a bootable SLC54 ia64 ISO image here:
http://linuxsoft.cern.ch/cern/slc54/ia64/images/
which I believe is intended mainly for network-based installs, but today I discovered I can use this as boot disk to begin the installation successfully. Alongside the HTTP and FTP options for network installs, there is another possible option for installation files contained on CD. Making that selection, it looks on the boot disk and fails to find the installation files, at which point it ejects the boot CD with a prompt to insert the CD containing the installation files. I found I could then insert the non-bootable DVD disk, click OK for retry, and the installation would proceed forward normally !
Maybe this was the intended method all along for installing Scientific Linux CERN, and I shouldn't have expected the SLC ia64 DVD installation disk to be bootable in the first place? Anyway, the 2-disk solution (bootable CD-ROM plus non-bootable DVD) works just fine.

Since my concern here is with the 64-bit "ia64" (Itanium 2) not "x86-64" (EMT64) version of Scientific Linux, in particular that produced by CERN as "SLC" (Scientific Linux CERN), I'm not certain how many of Larry's cautions will apply in my case.
I certainly echo his endorsement of "BeyondCompare", which has a 32-bit Linux version available as an RPM that installs straight away on i386 versions of SL. Some months ago I posted my method for installing it on SL 64-bit Itanium-2 machines using the IA32 Execution Layer (ia32el) emulation package here:

in case anyone else is interested.

The below statement makes it seem that your are trying to burn the ISO
"image" file (which contains a file system) within another filesystem
(ISO9660 etc). That is not correct. Your burner software should have a
function to burn a raw image file to the DVD without using any file
system. If you mount the DVD in a Windows or Linux machine and see a
single file, the ISO file, in a file browser, then it has been burned
incorrectly.

Assuming it's pilot error on my part, what DVD file system disk format
*should* I be selecting when using Roxio MyDVD to burn this ISO file
onto the DVD+R disk? (ISO9660, Joliet/ISO9660, or UDF ?) I selected the
default in the MyDVD application, but wonder if I should have chosen UDF
instead ?
