Actually, they talked to Scientific Atlanta/Cisco and got a box that plugs directly ontop of a tv box to be able to completely control the tivo box. It also allows for it to enable the ppvs.
TiVo's patent isn't on the ability to record, but an implementation to do it on low cost hardware. This makes it possible to support simultaneous recording and playback with trickplay in a $15-20 chip.I dont get TIVOS argument. I mean my VCR from the 1980s could be programmed to record a show at a certain time.
