It is true - you can do SD resolutions with digital TV. However, what I was alluding to was that, in the United States, people associate "HD TV" with "widescreen", and with DTV you typically only find digital SD resolutions when displaying legacy NTSC content (hence it's in 4x3). We're just not used to the fact that everywhere else in the world, people have had widescreen television long before there was HD or digital TV. Like I said, I would be thrilled to see more content providers properly denoting widescreen NTSC content. It's pretty frustrating watching a "widescreen DVD" on an "widescreen television" and still getting black bars on the top/bottom (and currently the only way to work around it nowadays is if the television is smart enough to heuristically detect the black bars). If they had actually followed the recommendations in EIA-608 (setting the aspect ratio in the line 21 VBI data), none of this would be a problem. Devin -- Devin J.
