I have my TiVo Premiere Elite hooked up to my home network via powerline. The powerline is good enough for Netflix and Amazon On Demand streaming. TiVo is on the first floor, and my wireless router is on the second floor. Instructions say that TiVo should be hooked up via Ethernet or MoCA, and MoCA is not an option since I have a cable company supplied amplifier on the Premiere's cable leg.
I have Cablevision's supplied app for viewing on the iPad, and have TiVo Desktop Plus for copying to iPad (subject to CCI byte).
What additional functionality will the Stream give me?
