Oh it's a bootleg.
It's using badly translated fansubs. The subtitles are hardcoded. The menu is one screen. It has seven random episodes instead of a full "arc". And the logo looks like it was blown up from a GIF. The region, as reported by the disc, is 1, 2, 3, 4, 5, 6, 7 AND 8. (Not just 1 through 6 like many R0 DVDs.)
Oh yeah, and it has Jimmy Neutron on the bottom right corner of the front cover.
This is a printed disc, not a DVD-R, which is weird but... I think there's duplication factories down here and since Mexicans will turn a blind eye to anything as long as the money is right...
