Can you help me solve an ethical dilemma?

So my gf really wants a copy of dvds of an old tv show, which wont’ be released anytime in the forseeable future. They sell dvds off of websites, but i’m sure they are just bootlegs.
My problem: I’m a musician, so i feel strongly against pirating music and movies. I want to get the dvd’s, though.
Can fluther help me figure out how to reason my way out of this?
