The commercial industry must have breathed a huge sigh of relief when online stores such as itunes arrived. Much of their "1080p" video is actually 1916x1076 or thereabouts, or 1280x716 for "720p" etc.

My personal obsession is to make 1.333 the "minimum" aspect ratio. If you only crop the black from many older 4:3 DVDs, you'll often end up with aspect ratios such as 1.32 or 1.30 etc, so I prefer to cop a little picture top and bottom if need be to make it 4:3 again. Wider than 4:3 is even better if possible.

That part of the conversation was referring to using the Avisynth resizers for cropping. They even accept float as cropping values so they can theoretically do sub pixel cropping.
