[Q]MYV - 25 Shunen Kinen Koen Tokyo Geijutsu Gekijo 5 Days ~Dokusou~

[xiaou-xijiang]

I'm up way too early to be sane, but I've got a question and its been bugging me for months!

I've got the taiwan ver. of the DVD 25 Shunen Kinen Koen Tokyo Geijutsu Gekijo 5 Days ~Dokusou~
Wikki states that

extras include behind-the-scenes footage and a documentary about the five-day concert series.

How do I get to that? there's a link at the top on the main menu (right below Play All) that might've been it but its just takes me to the first preformance: 'Selfish Love' and then when I wait after the whole credits it just takes me to the menu again.

The Taiwan ver. should have the features as well, seeing as how it describes the extras on the back. Any ideas?
