Manga Entertainment is a distributor of anime in the United Kingdom that began releasing One Piece on DVD and Blu-Ray in 2013. In May 2019 they were acquired by Funimation, the North American rights holder of the One Piece anime.
As of 2018, Manga Entertainment has released the first 491 episodes of the TV series and eleven of the Movies.
Manga's release of the One Piece TV series is identical in content to FUNimation's American releases, including the logo and credit alterations. Collections 1-13 use the PAL masters created by Madman, whereas Collection Fourteen onward are identical to the NTSC discs released by FUNimation (even refering to the US season releases in the menus). These releases contain audio in English 5.1 surround and Japanese stereo, and use the same subtitle translations as FUNimation's releases.
The 'In The Booth with Brina Palencia' special feature, which was advertised but not included with the US release of Season Five: Voyage Four, is included in Collection Thirteen. The Marathon Mode option is missing from the first thirteen collections. Otherwise, the extras are identical to their US counterparts.
The movies previously dubbed and released by FUNimation contain the English dub and original Japanese versions, whereas the others contain the Japanese version only.
The movie packs use Manga's own masters with alternate subtitles that occasionally use names and terminology inconsistent to the FUNimation translations.
With Manga's first release of the series, several reviewers noted the high fan demand for an uncut DVD version following FUNimation's acquisition of the series in America six years earlier and praised Manga for licensing the series. Like the FUNimation releases, the uncut version and the FUNimation dub were considered vastly superior to the edited 4Kids version that had aired on TV. Manga was also praised for releasing the series in the 26-episode Collection sets rather than the 13-episode sets that were released in America and Australia.
Some reviews criticized the earlier DVDs video quality for including noticeable compression artifacts such as macroblocking, although these problems were noted to be less apparent in later volumes, particularly once the DVDs started using HD masters.
The inclusion of the English 5.1 mix and the high quality soundtrack of both versions, however, was widely praised. The reception to the Extra Features have also been mixed.
While Manga was praised for licensing many of the movies before other English territories, the quality of the Movie Collection DVD was considered disappointing. The first Movie Collection was criticized for having poor video and audio quality, as well as having translations that were not consistent with either the TV series DVDs or the other movie releases. Reviewers also noted numerous errors on the box for Movie Collection One, advertising an English dub, 5.1 audio and the short Dream Soccer King that weren't included on the DVD. The video quality was noted to improve on the other two Movie Collections, but reviewers were still critical of the releases "disappointing" stereo soundtrack with "music and sound effects overpowering dialogue to the point of burying it completely"  and subtitles that contained even more grammatical and translation errors. These problems were carried over to the Blu-ray release of Movie 8. Movies 10 and 12 were praised for having picture, sound and subtitle quality on par with the FUNimation releases.
