Is there a website that list new movies released in HD-DVD/DVD combo format? While I don't have a HD-DVD player now, I think it is better to purchase new films in this format, as it sort of future proof your collection provided HD-DVD is not rendered obsolete by Blu-ray.
Most of the time, the price difference between the regular DVD and the HD-DVD/DVD combo is just a few dollars. And I gladly pay the difference to future-proof my collection or go through the hassle of selling my old depreciated DVD and buying the new High-Def version...
