I recall back in the 1970s (and even 80s) when it was common to see a movie broadcast (generally a spaghetti western) from a scope print with a flat lens.
Everyone was super thin. Sometimes this was just done for the opening/closing credits, other times the whole film would be shown that way.
You can still mimic this by setting your DVD player controls to "think" that you have a different type of tv than you actually do.
Which brings up ANOTHER beef about DVDs. I've seen several production companies that automatically ASSUME I have a 16x9 tv. I have to toggle my DVD player's setting just so that I can move the cursor over the appropriate DVD menu options.
Not every movie collectors want are even available in LD. There have been many recent movies, i.e., LOTR trilogy that isn't offered on LD.
That's why I enjoy both formats. Heck, I even own DVHS that offers both video and sound in the best quality offered for home video today.
