Splinter Cell 2 prb

[doohoodogg]

Man, i have an unusual prb. I have SP 2 original dvd and i wanna make a backup cause its already kinda dirty/scrached. Heres the prb: Ive tested it and theres no protection, only that insert cd string, so ive made an image with alcohol120 an burned it to an blank dvd, but when i insert that dvd nothing happens, the dvd its like emty but its not, its clearly visible that 2gigs is used. Ive tried on an RW dvd (same manufacture) and voila, the dvd is working, and then ive made a copy after the RW dvd on an DvD+r (same manufacture) and tha same problem like the first, the dvd appears emty. So whats the prb ?
how can i make a copy after that god ....... game ?
srry for my bad english
