Ive done a search for this but have not seen this mentioned anywhere. I havent been able to tell if this applies to all videos or just certain ones. Certain videos Ive come across play at a different aspect ratio and quality relative to how you are connected. Just an example, watch this clip (30 seconds long) on wifi, then watch it on edge. http://www.youtube.com/watch?v=l-NfrBgYIEQ This isnt some magnificent discovery, but its interesting nonetheless.
