Post 1 is now updated with as detail much as I know.
As and when I am told of any corrections to make or additions to add, I will amend that post.
The thing that suprised me was the lack of available subtitles.
I was also sure that a full set of "Commentary for visually impaired" were available and that either the DC commentary track or a modified 2004 DVD commentary track were available too.
My memory must be playing tricks on me!!
