I guess it's been resolved. No details about what exactly that means beyond Marty being able to post videos again, but at least it's over.

His Destiny music may remain inaccessible for the forseeable future. But in a YouTube comment, O'Donnell is hopeful that this latest ruling will let him begin reposting old Halo tracks and musical doodles.

Going off Marty's tweet it looks like it was over royalties on the TV show?

Yeah, if memory serves, Marty and Michael had a very different rights contract for their work on Halo than a lot of other contributors. Microsoft didn’t honor this uniqueness when property ownership changed hands and Michael and Marty we’re not paid as the rights holders for their work in subsequent media uses.

This seems to be the he best outcome
