Dragon Box Z Volume 1 - "Clips from foreign dubs"

[omegalucas]

So, I don't own the Dragon Boxes myself but I checked online out of curiosity the contents of the extras disc for the Japanese Volume 1 and found something interesting.
As mentioned here in the website, one of the extras is a series of clips from several foreign dubs, like the US, France and Portugal.
The first clip of that extra is supposedly the Spanish opening. The "intro card" actually shows the Spanish flag. So, I was expecting this to play: https://www.youtube.com/watch?v=yir9PZzlCKs
However, to my surprise, THIS started playing: https://www.youtube.com/watch?v=yWgWhuN8wc4
This is not the Spanish opening, but Brazil's.

So, I wanted to ask if anybody here who actually owns an official (physical) copy of the Dragon Box Z Volume 1 set can confirm if this is correct. As it is quite a strange mistake Toei/Pony Canyon made there.

Even I had a wtf moment when they played the Portuguese version over Spanish, also isn't there more than 1 Spanish dub?

Can confirm. It's a well documented error, pretty sure the site mentions it somewhere too.

Apparently not in the review (that was inherited from the old Kanzentai, I think) nor in the "My Dragon Box isn't Perfect" feature.

Maybe I'm misremembering.

Either way, it's at least been brought up multiple times on the forum in the past.
