DXC objective is to back up the whole movie, menus, trailers, extras and all with one click, this was the first all-in-one software to do so.
CloneDVD will not back up a protected DVD, so that's pretty much none then, which means you have to rip it off like with DVD2one.
Not tried it yet as I'm ripping X-Men with smartripper before it will do it's stuff, cos it complained of X-Men's CSS protection.
Why take a back-wards step like this when others have already stuck their necks out?, rather than break the protection use it in the back-up so that it cannot be copied easily and as with DXC will not back-up a back-up.
And of course when there are excellent free copiers like DVD shrink, why pay for this?
