I copied my discs to my harddrive and created my own link tot he main program section to choose year of each disc.
Its very simple to load it now,a nd I dont have to have the computer flip out when I insert the disc. Works like a charm.
As for the info yeah a lot is weird with it, but, mine so far has proved useful.
