Which part is illegal? Recording it? No. Burning it to a DVD? No. Owning it? No. But can I sell it? No. I think this paradox of ownership without being able to sell it will cause ReDigi to lose their case. Horrible situation for setting a bad legal precedent.
Let's not forget that the MPAA is a criminal organization whose members commit fraud every single day. I suspect the RIAA is the same. "Hollywood accounting" is a nice euphemism for a felony crime. I have no sympathy for unethical criminals who as standard business practice screw over producers, musicians, writers and actors. Piracy is justified.
