It has just come to my attention that the various UK Bluray releases of Attack on Titan AKA Shingeki no kyojin: Season 1 (TV) by Manga Entertainment Ltd have some errors that will be corrected in the upcoming Crunchyroll Steelbook Re-Release:
1: The Brightness Levels for each episode are higher than they should be.
2: The Subtitles are actually Dubtitles based on the English Dub track, instead of direct translations from the original Japanese Audio track.
3: The font and brightness level for the Subtitles are darker than those used for the US release of Season 1.
4: The font for the Subtitles are completely different to those used for the US release of Season 1.
5: The Chapter stops in both the Original and Re-Released versions are wrong and have both incorrect timings and completely the wrong titles.
6: The Manga Entertainment Ltd Bluray and DVD Part 1 and 2 releases have certain extras on a DVD instead of the Blurays but the 4-disc Bluray only Complete Season 1 re-release from 2016, re-authors the discs so all the extras are now on the Blurays in 1080p instead of some of them being relegated to a DVD. Also, the booklets from the Part 1 and 2 sets were dropped from the 4-disc re-release.
If needed, I can submit the full specs for the 4 disc re-release by Manga Entertainment Ltd, just let me know

Side Notes:
- The Home Video versions of Seasons 1-4 have significant differences compared to the versions shown on Streaming Services and Japanese TV when each season first aired: https://www.youtube.com/playlist?list=P ... 8k1zEac9sq
- The Crunchyroll and Funimation Bluray releases of Attack on Titan: Seasons 1-4 are all dual coded for Regions A & B and the DVDs are dual coded for Regions 1 & 2.
- The disc art for the discs in the Steelbook re-release, erroneously state they are Region B only, when in they are in fact dual-coded for Regions A & B.
