Hi-def? I'm sooooo beyond that

I'm a geek. Love me a bit of tech (iPhone excluded. I just don't get that one) and now that I have a Playstation 3 I'm seriously getting into watching films and series on Blu-ray. Lost Season 4 was great, for example.

However I won't be buying Weeds season 4 on Blu-ray. Don't get me wrong, it's an excellent series, but I already downloaded it in HD from the interwebs. Nine months ago. Surely releasing it a little earlier would have been a good idea?

Anyway, for those who haven't seen season 4 (coming out in June, a year after broadcast of the first episode), Blu-ray would be the way, but what struck about the sleeve art is that tagline at the bottom - BEYOND HIGH DEFINITION. Now when I mention Blu-ray to most of my friends they invariably reply with "Uuhh?" and ask what it is. When I say that it is like DVDs but in high definition, they ask what the difference is. Most people are so used to downloading DivX copies of films and series that high definition hasn't even entered their minds. And manufacturers aren't helping by suggesting that we are already beyond high definition.

My mother-in-law can't even set the time on her VCR yet. I'm not expecting her to be "beyond high definition" any time soon.
