A DirecTivo. The only reason it needs the phone is to order PPV. The software will also disable itself (the TiVo goodness anyway) if it can't make a call within a certain period. One of the few "NoPhone" hacks will solve this. A DirecTivo can also be connected to a network and forced to call that way. Both series1 and series2 as far as I know (must install nic into s1 and hack (enable) USB ports and add external usb-ethernet adapter for s2).
