Yu-Gi-Oh HK-DVD questions

[snappy]

First I want to lay this down:

Yu-Gi-Oh Series 1 JAP = ?
Yu-Gi-Oh Series 2 JAP = Yu-Gi-Oh Series 1 US
Yu-Gi-Oh Series 3 JAP = Yu-Gi-Oh Series 2 US

I have bought Series 2 (JAP)/Series 1 (US), the Hong Kong DVDs from Anime Video which advertise it as "Series 1". It is about duel monsters. "Series 2" Anime Video Hong Kong DVDs is about duel monsters aswell, the ending of it all etc.

Now I know there is 2 releases of HK DVDs out there, that say "Series 1".

Manga International sells a set.
Anime Video sells a set.

I want to know if Manga International DVDset is Series 1 (JAP). Yu-Gi-Oh! before the duel monsters was about Yu-Gi in school, getting the millenium puzzle, fighting off bullies, etc. This is the series I am mostly interested in, and I am not sure "what" is included in the Manga International "series 1". It has the same amount of episodes to Anime Video, and thats all I really know.

Anyways I would really like to know.

Thanks!
