So it sounds like since both k3b and Mytharchive both use growisofs, there
is nothing special or unique about an iso ripped via Mtyh, correct?
This then implies that I should be able to move the ISO to another
computer and burn via K3b. (correct me if I'm wrong)

I know that k3b CAN play an encyrpted DVD, and I have been able to mount
the ISO mentioned above via losetup and play the ISO image using k3b.  So
I am fairly confident it is a good ISO image.  Yet when I burned that same
image using k3b the resulting DVD would not play correctly.  I will try
your suggestion below of trying a slower speed.

BUT my what I really want to know is how to have Myth burn the image onto
a DVD with out moving the ISO to another computer.  I feel like I must be
looking over something obvious.  Can someone point me to an howto, or
explain this process.  I have spent 2-3 hours messing around in
Mytharchive and I just don't get it.

Thanks,
