Just found the dvd import of Queen live in Yoyogi National Stadium, Japan in 1985. Got it at Best Buy for $13. Have not watched it yet. It's 1:28 long, presented in 4:3 and I don't think it's 5.1.
Looks like it's imported from Mexico.
Yes, I've seen it in my local music shop here in Mexico. It should be this one: link
There's also live in Rio: link
I would expect them to be the same transfers of the Brazilean releases but I haven't bought them.
