Whoa. That was some link. Another evening lost to in-depth research. :D
Very interesting to learn -- all those early TV shows (60's+) were shot over-framed (like the above Star Trek demonstration), only with "4:3 protected" for broadcast on their day's TV. Unexpectedly forward-thinking. (Thread OP HDvision is my new hero!)
