I got an old Croutching Tiger Hidden Dragon DVD that is scratched. The first hour and a half, the dvd works fine. 15 Minute before the final fight scene, the dvd starts skipping and the picture gets all choppy. im using my ps2 to view the dvd on. i dont have any other dvd players in my house. i tried to use rubbing alcohol to clean it, and it made it a little better, but the dvd is still skipping. is there any trick out there that anyone knows about, in order to make the dvd work again? i konw there is a product out there that "shaves" a millmeter off the surface of the dvd, but it costs 19.99, and is not worth buying in order to fix my dvd..... ?
