Halo 3: ODST Xbox Live question?

[???]

Is Halo 3: ODST Xbox live seperate from Halo 3 Xbox Live?
In other words, if I were to play Halo 3:ODST Xbox Live and my friend was playing Halo 3 Xbox Live could we play in the same games? Or are they treated seperate?

they are the same. The Multiplayer disc that comes with ODST is the the HALO 3 multiplayer. So basically its the same, you two go have fun.
