I haven’t switched to Hi-Def discs yet. With the HD-DVD \ Blu-ray saga continuing, my guess is that hybrid players will actually solve the main issue of what format to opt for anyway but hey what do I know? I found it interesting that the former chair of the Society of Motion Picture and Television Engineers doesn’t like Blu-ray because Sony (the company behind Blu-ray) refuses to use any video compression technique on Blu-ray other than the already surpassed MPEG2 codec and from a geek point of view I tend to agree and would go for HD-DVD if I had to choose at the moment. Still, I sit on the fence and compile my list for future purchase.

The arrival of the Blade Runner final cut in December could weaken that stance however, especially given that the five disc ultimate collection will only be available in numbered briefcases. OK I’m a big fan, but Blade Runner is one of those remarkable films that will always be better on the big screen and hi-def is that one step closer to it.

The film companies aren’t stupid either. They know there’s a big sci-fi \ tech geek crossover and a lot of early releases have been sci-fi films with established followings. Case in point, Serenity was the first of them all. Plus, they know that they can re-release the discs later on with better extras and we'll splurge again.

So what’s worthy of the HD treatment then? Well, these are and given their extraordinary visuals and established status, these will be well worth the investment.

Aside from concert dvds, what other genre pushes the boundaries of visuals and sound that sci-fi does? What other genre will really test your nascent HD system. Enjoy.
