I bought Stuart Little 3 from big w and my pc wont even load the dvd,likes its a blank disk :-( Ive tried upgrading dvd writers firmware etc

tried Clonedvd2,anydvd,dvd decrypter etc all the programs .. but when i put dvd in drive it just attempts to read it then nothing. I can click on dvd drive icon on desktop and window opens but nothing to view....

ive copied many purchased dvd movies and made backups before with no problem...

the movie plays 100% no problems on setop dvd player but wont play or even read on pc with powerdvd etc ....

its a Sony pictures movie ....

Ive heard theres new protection ... but does sony realise many people dont own dvd settop players ?? alot of people play movies on their pc .....

Is there anyway to copy this movie ????
