There have been two DVD releases of The Headmasters, Chojin Masterforce, and Victory.
First, there are the ones released by
Metrodome in the U.K.

TFWiki.net wrote:A four-disc box set collecting the entire Headmasters anime series. The set features the original Japanese audio track with newly-created (and inconsistent) English subtitles, with the infamous Omni Productions dub as a second option. The masters supplied to Metrodome proved slightly incomplete, however, lacking the "next episode" previews, and the few segments that come before the title cards of certain episodes. The set features audio commentaries on three episodes by UK fan Chris McFeely

TFWiki.net wrote:A five-disc box set collecting the Super-God Masterforce anime series (omitting the clip show that was broadcast as the final episode of the series in Japan). This set includes only the Japanese audio with subtitles, this time translated by Jordan L. Derber. The set again features three audio commentaries by McFeely. Cover art by Nick Roche.

TFWiki.net wrote:A four-disc box set collecting the entire Victory anime series. As with Masterforce, the set includes only the Japanese audio, subs by Derber, and three commentaries by McFeely. Notably, the set omits the six (!) clip shows present in the original broadcast run of the series, featuring only the core 32 episodes. Cover art by Nick Roche.
And the above three sets compiled together in one set.

Second are the ones released by
Madman in Australia.

TFWiki.net wrote:Four-disc set featuring the Headmasters series available in the original Japanese and the Omni Productions English dub, with optional English subtitles replicated from Metrodome's previous release, complete with errors.
Extras include a "making of the cover" gallery, character art galleries, toy galleries (taken from Seibertron.com) and Japanese toy commercials.

TFWiki.net wrote:Four-disc set featuring the Victory series in Japanese with English subtitles, with optional Omni dub on all episodes, plus the Zone OVA.
Extras include box art galleries, toy galleries (with pictures from seibertron.com and transformerstoys.co.uk) and Japanese commercials (which are all for Zone toys, and include what appears to be an industry pitch reel used to demonstrate the toys to retailers), as well as scans of the TV Magazine Zone story pages available via DVD-ROM.
In keeping with Madman's dodgy enthusiasm there's a bunch of seemingly random (sometimes translated, sometimes not) scans of manga and story-page material for Battlestars and Operation Combination included in the set as well.
And the above three compiled together in one set

TFWiki.net wrote:To capitalize on the release of Revenge of the Fallen, all three of the Japanese Generation 1 sets were re-released in one package at a lower price point ($99.95AUD versus $150-odd AUD).
HOWEVER, there is a third, much cheaper option: TV-Nihon's fansub releases of
these three series (which are free to download via torrent download or direct download). Their Headmasters subs do not contain the errors that both DVD subs have, and they include all the missing footage from the DVDs of that series as well. Their Masterforce subs include the missing special episode that aired at the end of the seires, and their Victory do include all 6 broadcast clip episodes.
