I don't believe "World" exists for DVD. Even though it may be all region, the video fps would be different based on region. I'm presuming this should be USA region.

I'm guessing that he used the supported regions as the basis for his submission. It has support for Regions 1 2 3 4 5 6 8, where 7 is an unimplemented region.

I agree that it probably shouldn't be World though. We'll need to talk to limbo43 about this.
