HD vs Blu-Ray

It has come to my attention why I have to take a stance on Blu-Ray or HD. I had thought I would cheer for the Blu-Ray, because in storage space matters, I was watching CNET Video blog on the debate and they braught one point that will definitly push me toward the Blu-Ray. The Big factor - Blu-ray is trying to prevent everyone from replicating porn. They all said that they don't in anyway duplicate Porn. For this alone. SONY has gotten a huge boost in my books, even if they don't support macs.
