I just bought "Hot Fuzz" on DVD. Inside was a little flyer advertising HDDVD. It said that all HDDVD's include HD on one side & DVD on another. Is that true? Does EVERY HD DVD include SD DVD for DVD players on the other side? If so that's awesome... I'd start buying HDDVD's instead of DVD's for movies I like so I can get a duel format player later.
