Problem extracting files from DVD ISO

I tried both the built-in 7-zip 9.04 (part of Debian) and new BETA v9.38.1. (compiled from source)
Here I give 2 outputs:
one is good, successful extraction of data from openSUSE 11.4 x64 DVD ISO.
one is bad, unsuccessful extraction of data from openSUSE 12.1 x64 DVD ISO.
I know, that both DVD ISO images are good, and can be booted & installed in VirtualBox.
I know, that all 3 files exist in both images, checked via loop-mount.
I do not know how those ISOs were created. ISO level3/Joliet/Rock-Ridge ? No idea.
Anyone has any idea why ?
Good example:
root@deb6-xrig:/tmp/suse121# /home/alexey/7z e /D/OSes/openSUSE-11.4-DVD-x86_64.iso boot/x86_64/loader/initrd boot/x86_64/loader/linux boot/x86_64/loader/isolinux.bin

Any ideas?

And, if this problem cannot be fixed quickly in 7zip, which alternatives do I have to extract files ?
(without root permissions, so "mount -o loop ..." doesn't count)

I need direct link to download for that "unsupported" file.
Here. The download is rather slow for me - less than 300 KB/s. Torrent download may be more appropriate.
As far as I know ISO format, OpenSUSE images use HDD emulation for booting. For example, OpenSUSE 13.1 provides two partitions:

However, 12.1 has boot sectors at DVD LBA 850 (isolinux) and 55110 (UEFI), whereas 13.1 uses LBAs 5980 and 941 correspondingly.
I'll fix that problem in next version (7-Zip 15.01 alpha).
Thanks!
openSUSE-12.1-DVD-x86_64.iso
contains two boot entries:
1-Boot-NoEmul-Legacy (isolinux).img
2-Boot-NoEmul-UEFI (elilo).img
And 7-Zip incorrectly parsed some fields for such case (boot image entry with special id string field: Vendor unique selection criteria).
