Okay, well I took the question to be a bit more specific than that: TiVo's main competition is the Moxi HD DVR, and (essentially) Windows 7 Media Center Edition. Both of those options offer low-cost boxes on remote televisions, the Moxi Mate and Media Center Extenders, respectively. So you still need a special box on every television, but with those other options, you don't need a separate DVR on every television, you just need a separate extender box. Of course, in those cases, you'd be well-advised to hard-wire your home for Ethernet, something which a lot of folks consider to be too expensive to consider.
