Note that rights to stream a show are different to releasing it on "home video". I'm not sure of the full legalities, but I think it is something like streaming is closer to broadcasting. Eveidently, most shows of any vintage were created with contracts that covered broadcasting re-use, but only those made in the post VHS-era have clauses covering home video, whioch is why they are so problematic because they have to go to everyone involved to negotiate the rights, royalties, and even a minor character can act as a block (and sometimes their estates) Marine Boy is confimed? Where? I would be very excited if it is! Suprised TVShowsOnDVD haven't run the story if it is the case. As you say it's a large series with 78 half-hour episodes. It seems somewhat large for an MOD release. The previous release of Centurions, which gave us just the five episode starter series but not the vast bulk of the later episodes, does not fill me with optimism.
