check media integrity option for DVD

[elcaset]

It would be great to be able to check media integrity of the DVD. Some other distros like PCLinuxOS & Kubuntu include this option when booting off of the live disk. This way you know weather there's a problem with your burned install disk or not. Thanks very much for Sabayon. It works for me on PCs that won't boot any other distro except really simple ones like Slax & Damn Small Linux.
