I'm going to have a party at my house soon, and we do NOT have a blue ray player. I don't own the movie we're going to watch, but I plan on either renting it from Charter on Demand, or from Amazon online. My question is, when I rent the HD version on Charter on Demand (for a couple bucks more), does that HD quality equal the quality of a blue ray player, or is it still less? Same for amazon. If no for both, is there some way I can, or will I have to borrow someone's blue ray player.
