Standard-definition television (SDTV) has a 4:3 (1.33:1) aspect ratio, although in recent years many broadcasters have transmitted programs "squeezed" horizontally in 16:9 anamorphic format, in hopes that the viewer has a 16:9 set which stretches the image out to normal-looking proportions, or a set which "squishes" the image vertically to present a "letterbox" view of the image, again with correct proportions"

Ok, so according to that I am not watching HD when I am watching Iron Man on Blu-ray because that has an aspect ratio of 2.35:1. Also, just noticed, that quote is wrong about one thing. 2.39:1 is an actual aspect ratio as is 2.35:1. There are even greater ratios of 2.70:1 (Ben Hur was shot in that).
Re-reading the quote again, that has no bearing on what I was saying. Video and Film generally refer to two different things. When somebody mentions film they are talking about a movie shot for the theater. Video is what is normally used for television shows (like CSI, Sports games) which have an aspect ratio of 16:9. So all that quote is saying is that shows shot in HD for TV really, has an aspect ratio of 16:9. The next part says that movies shot in widescreen (pretty much all new films, except for a few) can be shot in anything from 1.66:1 (Disney does this) to 2.39:1 (or greater if the director wants to).
