Why not in Wide Screen?

Rating: Null/10 (9 January 2006)

I have seen Gone With the Wind 3 times in theaters and always in Cinerama, the 70mm format with very good sound. I have also seen it in standard screen and the impact of the Movie is much greater in wide screen. I am wondering why it is only available on DVD in so called Standard Format? It was originally available in super-wide screen in theaters.
If ever there was a movie that should be on DVD in Wide screen it is this one. The spectacular scenery is just lacking in so called "Standard" screen.
Do the masters to create a restored wide screen DVD exist? Howard
