My Mini Dvd Is Not Working And It Keeps Freezing Up My Computers!

I tried putting the dvd into different computers to see if the driver was broken in my laptop. my drivers are fine, because the flip side of the dvd worked.then i tried to use a dvd repair method i found online. they said to put it through dvdfab and it will clear up all the problems. no luck, it spent like two hours processing and nothing happened.then i decided to clean the disk. i used soap and alcohol. i think that helped because when i put the disk back into my laptop, i was able to see some of the video files on interactive player. however, i was only able to use interactive player, and it was really slow. it froze up several times.then i tried to play the dvd whilst filming my computer screen, in order to get the footage. but the dvd keeps causing the players to freeze up. i'm trying to find a different method now.please help me, i really, really, really, really need this footage
