this movie here is over 7GB for all the files in the set and over 8GB after the iso file is extracted. something that is only 2GB, there is no way it is DVD quality.
widescreen is like 16:9 or 16:10, i forget which, and full screen (a.k.a. pan & scan) is 4:3 I believe. No such thing as 1:1, that would be a perfectly square picture.
