Perhaps, but as I said before it's common sense that adding the complexity of multiple layers to a DVD is inherently less likely to be reliable, and making reliable DVDs is enough of a hassle without that. Plus there's no cost-savings for using one dual-layer disc versus two single-layer, other than reducing time for the initial setup. In any case, I'm glad that a single-layer Blu-ray disc can hold a lot of HD content in a format which is quick and easy to render, so I'll prefer that over trying to pack HD material onto a red-laser disc.
