i'm not an expert on this stuff of course, but I'm imagining that the H.264 codec is 'scalable' - it can convert to any video quality upto HDTV & down to ipod video. Yes, the codec is scalable in that it can target anything from an iPod up to HD. Most codecs don't scale that well from an encoding standpoint but where people get confused is that once a given piece of content is encoded (say at iPod resolution) it won't be rendered at a higher resolution any more than any other codec (i.e. it can be scaled to a higher resolution but there's no magic that will all of the sudden display more detail.) Sophisticated software is needed. Any Mac (or Windows PC, I believe) with Quicktime 7 can do this.
