[DVD-o-matic] Feature: Any aspect ratio into flat or scope

Carl, a nice-to-have feature would be being able to stick any source aspect ratio into a flat or scope container -- via pillar- or letterboxing, if required. For example: NASA has amazing footage of the July 19 2012 solar flare event on http://svs.gsfc.nasa.gov/vis/a000000/a004000/a004026/, e.g. the 1024x1024 version (http://svs.gsfc.nasa.gov/vis/a000000/a004000/a004026/AIA304July2012rain_1Kx…), acquired by SDO's AIA. Apparently in 0.75-1 there is no way to maintain the source aspect ratio of that video -- 1:1 in this case. Or am I missing it? Wolfgang
