Original Single Disc versions of movies?

[Oantrek]

There are so many DVD releases of the Star Trek movies...Can anyone tell me which release or releases has the original theatrical releases of the first 10 movies with the special effects unchanged? The Widescreen DVD Versions released in the early 2000's? The 50th anniversary editions? Some other?

The Blu-rays are what you want you want to buy, specifically these two sets.

Regardless, every Blu-ray set with the exception of the new Wrath of Khan Director's Cut release (which also has the theatrical cut on disc and is far superior in terms of picture quality to the original 2009 master) is using the same master as these two sets, including the 50th Anniversary set, just with newer packaging (the 50th Anniversary set replaced the old WoK disc with the newer one, so there's a few benefits to buying that release). They might be missing a few extras here and there, but nothing drastic.

They all look mostly the same and are all the theatrical versions of the films.
