I have the following equpment:

- Yamaha RX-Z9 Receiver
- Directv DVR
- Scientif Atl cable box
- Polk XM reference

To what extent can I have 2-way capability? Right now I do not have an extender, but am looking to get as much 2-way out of this setup as possible. Can someone help me determine what's out there for what I have? I do not know how to write the modules so I will have to rely on whats in the market now. Thanks, greatly appreciated.
