Would it be feasible to write an application that does a bit copy of a DVD(eg. xbox dvd)? Yes, I've read the various articles on the xbox dvd encryption. From what I've read, it basically boils down to the directory header info being false(reports that a 2.6gb DVD is actually a 7 mb DVD).
But wouldn't it be possible to write an app that makes certain assumptions about the size of the DVD and then bit copy the data until a pre-determined size? I can hear someone saying now "how would you know the size?". Well, the ending format wouldn't(I think) be a big deal as there must be some report by the hardware that there is no more disc left(as opposed to no more filesystem left). In the worst case scenario, a person with a chipped xbox could find the sizes. If you already have a chipped xbox, why would you do this? One, it would definetly be faster than the current methods I've seen for burning backups. Two(of a more benevolent nature) sizes could be posted for people without mod-chips.
I'm not asking anyone to write this. I'm asking any programmers with experience, if it is feasible. I, once upon a time used to do C programming(late 80's), but I would be willing to take it up again to write this. I am looking at writing this as a linux app. Is it something a bit more low-level than user-space? Would I be looking at modifying the dvd kernel driver to achieve this? Is it just impossible for some reason I am ignorant of? Please reposnd to this post, as I would really like to know.
