I have the Multi-Room DVR option and Media Manager setup and runs fine. I can access my music and pics from the HDDVR box. My question: is that the only STB I can access my music and pics from? Or can I access from other 2500 STB's in my house? What if I get another HD STB (non-DVR) can I access from that one? is it only 1 STB per house?
