ripping a protected dvd

[Tyler_Durden_83]

first of all i wanna say hi to everyone since this is my first post!
then my problem....i bought a bootleg dvd of a show and i want to rip it, for personal use only. i ripped many dvd before and never had a problem but this one is driving me crazy. i tryed 4 or 5 programs and all were powerless (smart ripper, divx video duplicator, dvd decrypter...). it also gave me problems simply watching it and there is just one program that can see it correctly (power dvd, interactual player and some more couldt read it after a certain part, just windvd can read it all). at first i thought it was damaged but now im sure it has some sort of protection. how can i rip a dvd with a protection? is there a program that can rip it easely? or a program to find out what protection it has on and depending on this rip it in a certain way...? thanks to every1 who will help me with this!
