From what I had said above, I would conclude that ultimately an HD-DVD format is *mandatory*. You can only go so far with de-interlacing DVDs and upconverting them for 720 or 1080 line HD displays. The question of how best to upgrade is orthogonal. Should stores be required to double-stock their items, or should HD-DVDs also work in DVD players? Last I heard, DVD-As are supposed to be playable also on regular CD players, for exactly this reason. I don't know if this has actually happened, but that was the plan. It's another matter whether DVD-A or SACD will succeed. I don't know that the improvement is obvious enough to the masses. And this is because CD playback has been improved quite a lot just by tweaking the players, without having to change the standard itself. That's always the preferable route, as long as it's viable. From an engineering perspective, that is.
