Audio recorder for protected video softwares?


New member
Anybody watch animes here? I love the starting song in Witch Hunter Robin and i want to have that song in my 4G iPod. The thing is that video is copy right (dvd) and i can't find it online, not even sure what's the title of the song. I tried soundforge and it wont allow to open it... What other softwares i can use to get that song in my video????
