Ok.... I can't believe I'm sticking my foot in a format war thread... but here goes:

Isn't the biggest threat to either format not each other or even traditional DVD, but downloadable content?

I think both HD DVD and Blu Ray shoud be sweating now that Apple TV will be allowing consumers to buy/rent HD Movies from the comfort of their sofa. And I don't think apple wiil be the last company to provide such a service... I really think that downloads are in and physical media is on the slow crawl out (or at least to a niche market, much like vinyl)... I don't think the current MP3/4 generation is really that interested in a stack of optical discs lying around the sofa when they can just have it all stored in a tiny box attached to the tv...

As for porn.... I don't think it really matters whether HD DVD or Blu Ray adopts/doesn't adopt porn anymore... that was a major sales driver in the 80s but far less so now.... Yes porn viewing will and probably always will be a massive market, but I strongly suspect that most of the porn consumed today is downloaded/streamed (whether paid for or pirated)...
