TiVo unveiled the first working prototype of its upcoming CableCard-capable digital video recorder here at the Consumer Electronics Show. The new Series3 HD DVR will be the first non-DirecTV TiVo to record HD, and the first ever with CableCard functionality, which lets it record and playback encrypted digital cable broadcasts.
The Series3 is starting to hit the press, though there are some things in this article which contradict what I was told by the TiVo reps I spoke to. The unit does have a 250GB drive (though that could change before it finally ships, and it is possible that, like the Series2, there could be different models), but the capacity is up to 300 hours of SD and 30 hours of HD, not 250/25.
The article says this unit will not support MRV – but I was told by more than one TiVo rep that they do plan to support MRV, TTG, etc.
