If you want legal advice, consult a lawyer. My own personal opinion (which should not be taken as legal advice) is that fan-edits are, at best, a legal gray area, which is why you won't see one for sale at Barnes and Noble. Even if you own the Blu-rays and the GOUT discs, and you made all the edits entirely by yourself, they may not clearly legal in all jurisdictions simply due to DRM circumvention. So let's just be clear here: if you seriously want to walk the straight and narrow, just walk away.
Still here? Okay, download a torrent client (I find Vuze to be simple-ish), get an account at MySpleen, and knock yourself out.
