Goldenzrule is correct (I have 2 myself). There are instructions in the menu system on how to do it (menu, system, remote...). You can unplug one (worst case if they interfere) and set the other up to a different ID. The TVs are going to be the harder thing to control (volume, etc). If you have the funds, a professional installer (I'm not one) could set you up (seperate blasters for each item). You are only limited by how much money you have available to spend on this...
