For those who haven't played the FFVII game, watching the featurette "Reminiscence of Final Fantasy VII" is a requirement because it gives you an idea of the events that happened in the game. 
1 comment on the DVD though, the English subtitles doesn't match the English audio. What the characters are saying isn't exactly what is displayed on screen (subtitles).
maybe the english subs are "direct translations" of the japanese audio. and not meant as a sub for the english dub audio. (not 100% sure... but i think this is common for most english dubbed japanese anime?)
