Of course I knew it was a Blu-ray, just because I don't watch TV doesn't means I'm daft. ;) I bought it because it was $5 and my DVD copy of that movie is only a 1.33 aspect ratio.
Actually, I expected to have a Blu-ray player by now, but I've still as of yet never even been so much as slightly tempted to buy one. My DVDs look just fine on a 50" 1080p television (well, there are these three films I rather like that look like shit on it, but all the rest look fine), so I just haven't seen a point. And streaming HD seems to be making quite a scene, by the time I get around to needing to replace my DVD player, Blu-ray might not even be the big thing anymore. Not to mention, more often than not I am less than impressed with the Blu-ray transfers and their overzealous DNR in many of the films I'd consider buying.
