The 1989 (2 disk gatefold) and 1993 (Connery Collection Vol. II 3-film box set) laserdisk versions are the same print with the alternate mono soundtrack featuring the rare instrumental "Thunderball" end title theme. The secondary mono audio track on the Blu-ray has all these alternate audio variations except the "Thunderball" end theme. In it's place, the Ultimate edition and Blu-ray 5.1, and also the secondary mono audio track on the Blu-ray use the James Bond Theme for the end titles. It is also important to note the the color on the 1993 (Connery Collection Vol. II)is a bit better then the 1989 (2 disk gatefold) version.

The THX (30th Anniversary) Edition is important for a few reasons.

It has THX Laserdisk mastering, and is presented in Standard Play format and uses 5 sides for the film (sides 6 and 7 are the extras, and are in CLV Extended play). The 1989 and 1993 are only CLV Extended play, and use 3 sides.

This is the same restored print that was used for the S.E. DVD. It has lossless PCM audio. That version of the soundtrack is only available in remixed 5.1 Dolby Digital on the S.E. DVD, or remixed with additional sound enhancements in 5.1 DTS on the Blu-Ray.

Hope that helps.

As a side note, I want to create a new 2.0 stereo mix to match the original mono version. I will use the 5.1 mix as a blueprint on how to pan the sound in most of the scenes, but will not use the modern enhanced sound effect elements added to the U.E and Blu-ray. I also hope to use the stereo soundtrack CD's of the Barry score for the music mix. This new stereo mix will also be PCM lossless.

Right now, I am capturing the 1993 CLV version to my HD.
