This is the first time that the actual episodes have been officially presented in their original, uncropped, widescreen video format in any fashion. When they aired back on Cartoon Network, the video masters had been cropped to a full screen format, which is also what the DVDs used. Even when released in the Japan, the Japanese dub used the cropped full screen masters with some added background borders to "fill in" the missing widescreen space.
And now, for the first time ever, we are able to properly view the Transformers animated Cartoon in its original, unaltered, widescreen format with everything in full view, and in HD to boot! Here are some comparison screenshots courtesy of The Allspark.
