Unfortunately, as I've found out elsewhere on this forum, that won't work either. What is labled "full screen" can be something that is "pan and scanned" or it can be a film that was "opened up" and had the mattes removed thus giving more, sometimes unintended (such as microphones and booms), info from the top and bottom of the screen. When I suggested that a DVD be labled as "modified for 4x3 TV" or "OAR-original aspect ratio" I got comments, with examples, that the term OAR is variable, e.g. the difference between the so called "approved" AR of the DVD version of "Apocalypse Now" and the AR when it was first shown in the theaters. I am sure you've seen many times when posters have argued what the OAR of a film was and have pointed out that refs to an OAR in IMDB.com are known to be incorrect. Guess we have to try to come up with something we call can agree on.
