2xDVD5 works great on W7 x86, time taken: 2 pizzas + 6 beers
1xDVD5 will not work because the game has serious problems with non-original biks (I've tried to do this by few last days and on thousands ways).
The question is what's gone wrong when i've tried to use precomp+srep+freearc (mx) and couldn't fit 2 DVDs few days ago :/
