You'll notice these resolutions throughout the TV (now the "imaging") industry. It all comes down to the fact that we design pictures, ultimately, to be played on dumb machines that can't understand any other formats. It's the digital equivalent of sprocket holes. The processor, bandwidth, all of the multitude of parameters of any digital image, can in fact be adjusted, but you keep them to standards so that you can play it on your HDTV or STV or iPod with video. But you can tweak the signal processing, within a narrow range, which is important.

Do some transcoding with ffmegx, the Swiss Army knife of digital video processors. It took a while to learn it, because I didn't understand the "standard formats" business. You need to make a DVD with a strict set of dimensions, bitrate and signal correction, or it just won't play.
