Use to create DVD on ia64

[Zhang, Yanmin]

I created DVD image by pungi. disc1 is about 650M and disc2 is about 441M, but DVD is just
about 650M.

It looks like the doCreateIsos chooses directory os-disc1 to create DVD. Should it be os instead
of os-disc1?

Below small patch changes it. With the new patch, the DVD image is about 2.4GB, which looks like
too bigger (comparing with the total of disc1 and disc2).
