mediacheck??

next update... 

first, I can confirm all findings by Just18 and AS, also that enforcing to embed a md5sum more than once will corrupt the iso integrity check.
And here the latest weirdness: did a new FM-remaster with the boot-option mediacheck but NOT implementing the md5sum via mylivecd because I think the problem originates at this place. Then I added the md5sum later using implantisomd5 and I get this:

Inserting md5sum into iso image...
md5 = 2c900...somenumber......
Inserting fragment md5sums into iso image...
fragmd5 = cla15...somenumber...
frags = 20
Setting supported flag to 0
pclinuxos-kde-fullmonty-2011.10.iso Done

Next on this iso-image I run
a) checkisomd5: I do not get the expected Read-list but only "Press [ESC] to abort check" and finally: The media check is complete, the result is: PASS
b) mediacheck: normal progress window up to 100% and the result is FAIL
=> checkisomd5 supports fragmented md5sums while mediacheck does not. But we need mediacheck to have a graphic tool on the live-session 
But what are fragmented md5sums anyway?? Googling for this suggests to disable SELinux, which is not installed...

I implanted the md5sum from my remaster-script, meaning with root-priviledges. Will now do another test adding them as normal user, maybe that helps...

and the next update:
same results as before when implanting the md5sum as user: checkisomd5 PASS and mediacheck FAIL, meaning checkisomd5 works.
In mylivecd I will try to replace mediacheck with checkisomd5 and somehow pipe out the progress to a dialog window, which can then be displayed in a live-session. Let's see if that can be done...

final update: SOLVED 

the rpm-packages isomd5sum and mediacheck both contain checkisomd5 and implantisomd5 but in different versions and only the ones from the rpm-package mediacheck work with the program mediacheck. Since both both rpms were installed on FM mediacheck on FM crashed. Removing isomd5sum and using only mediacheck made mediacheck work again for the remaster. => Included the mediacheck boot-option in mylivecd and sent it to the boss.
