I hear ya mate. I don't think it's fair at all for this site to enforce such a ridiculous rule. If you don't have the funds to upgrade for blu-ray let alone spend the 50 to 100 bucks just for the movies alone, I think that you should NOT have to own the blu-rays if you already have the same versions on DVD.
However, since you don't have a stand alone player capable of decoding HD material, you will not be able to watch ADY's HD version of ESB:Revisited. That also raises the question of if Ady will release a standard definition version for the ones that cant playback HD content, and will they still need to have the blu-ray's to have a lower quality version of ESB:revisited.
