What ARE DVD Magazines?
Judging from the title...Magazines...on a DVD?
xD
Wow, I'm so slow, but could someone like, explain a little...more in depth what Morning Musume DVD Magazines are?
I'll try to explain it in genral.
DVD Magazines are usually released whenever a H!P group goes on tour. But also when they have stage plays or similar big events organized by H!P. They are also available for non-FC member since they are for sale at the venue of the event/concert.
The content of DVD Magazines is various. Of course though, MM DVD Magazines contain only MM, Berryz ones only Berryz, C-ute ones only C-ute etc.; except for rare guest appearances of other groups(-members). H!P DVD Magazines usually contain all groups participating at the H!P tour and it's usually Q&A stuff but there has also been other things in the past (like quizzes, or this "do an advertisement"-competition).
Other groups DVD Magazines also often have Q&A parts but often also have games or members doing stuff like going to some place and more, it's really random.
So yeah, they are like a magazine, showing you news about the group, what they are doing, what they are thinking, who is good at what (competitions). Some DVD Magazines are rather boring if you don't know much Japanese because they contain much talking in some studio while other are "interesting" because the group goes somewhere.
So if you are interested in MM members and not just their music you can download some from h!o tracker I guess to figure out what those are like by yourself.
