I know that B5 was filmed with the intention of ultimately being shown in widescreen (which is the version now shown on the SFC). But I also remember reading that both the widesreen *and* non-widescreen versions are cropped (top and bottom in the former case, left and right in the latter). Is this true? If so, why do they bother showing widescreen in these proportions? Why not just show it in the same proportions that it was filmed in?
