Advertisements I just got a brand new TCL tv. How on Earth does the tv know what I am watching on my TiVo DVR? I've done nothing that would make them communicate. Unless somehow through CEC the tv knows what channel my TiVo is tuned? That would make me think our tivostream4k can communicate with our dvr easily!!! What's happening is if I tune into the Simpsons the Roku TCL tv pops up a banner telling me I can watch this program from other providers.
