I can give information here
It's not a repack, but a new remaster. The original version's remaster got outdated shortly after the release, and it caused a ghosting effect when viewed on TVs.
This new version remasters the footage with a different technique named DIGITAL VISION PHOENIX and there is no ghosting effect. The NTSC masters were converted to PAL 576i (interlaced) in the previous version, and they're now PAL 576p (progressive). The audio tracks are the same.
The footage quality is slightly color-corrected Dragon Box: the colors are a bit (only a bit) brighter, and that pink tint many people complain about is not present.
The title cards are in Japanese. If they haven't changed it from the previous release, the NEPs are not included in the episode, but in the extras (there is a section called "unreleased previews"), and they're in Japanese with no subtitles.
But maybe someone who does own it can say it better, I can only talk about the previous release and the information available online. Maybe the NEPs are included in their proper place and subtitled in this version.
