Yes I have reinstalled things and I get the information you said with the right click....so the answer to my question "What are CSS keys for" is.........
AnyDVD keeps archives of all CSS Keys it has cracked in the registry if this option is enabled. This is done because cracking can take some time.
If you insert a DVD for the second time, AnyDVD will retrieve the key from the Key archive instead of cracking it again..
Thanks to all who posted reply I am slow but I will get there (With help)
