Your latter argument makes no sense, as installing the disk to the hard drive shouldn't have anything to do with whether the MP components are all on one disc.
The only reason Halo 3 has issues is they used their own method of installing to the HDD (temporary caching that's flushed when you play another game) which clashes with the new patch for copying the games to the HDD as it tries to stream from 2 location on one HDD.
