Do a google search with what you want and either the word hack or phrack.
Sorry, I won't give the name out because it is really illegal stuff. but I will say this.
You have to place the harddrive inside your pc to read it.
Then let your pc and this proggie decrypt the drive.(takes 6 - 10 hours).
But your still not finished.!
Once decrypted doesn't mean playable, it means all the code has been turned into hexadecimal code.
So now you have to read thru the code and find the parts of the video you want and copy and past the code into another proggie.
This other proggie will then combine the hexadecimal code and convert it to a playable MPG file.( this part takes about 3 hours for 1 hour of video).
Also, the first step also requires you to bring up your computer in DOS without windows. So you do have to know dos.
In reality it is about 6 hours of conversion time for every 1 hour of video on a 3.75ghz system with 8GB of memory. Add a couple of extra hours for each Ghz under this.
Is it worth it?
For the technical learning, yes.
For the video itself, HELL NO! It would be cheaper and faster to just go and buy the disc at a place like gohastings.
But phracking stuff up is a fun way to learn about the inner workings of things.
