The Spectrum website states the following: To install your Tuning Adapter, first make sure the CableCARD™ is installed and activated. Then follow these steps: 1. Connect the cable from the wall to cable in on the tuning adapter. 2. Connect a cable from cable out on the tuning adapter to cable in on the TiVo. 3. Connect the power cord to the tuning adapter. 4. When the light is solid (has stopped flashing) connect the USB cable from the back of the tuning adapter to the TiVo. Regarding step 2, is this the preferred connection method or is it better (as has been suggested elsewhere) to use a splitter to connect the TA and the TiVo each with their own separate cables.
