Can 1 TiVo Mini access two different TiVo Bolts on the same network in my house?

No, a single TiVo Mini can only connect to one TiVo Bolt at a time. While it can switch between different TiVo Bolts on the same network, you must manually change the connection in the TiVo Mini settings to access content from a different Bolt. Each TiVo Mini is designed to serve one host device at a time for streaming and recording.
