2-4: What Robert J said.

1. The limitations are that it cannot receive "Video on Demand" & "PPV" chs due to lack of 2-way communication capabilities. Also cannot access "switched digital video" chs for the same reason. Switched digital is a bandwidth conserving technology where the operator doesn't send all the channels all the way through to the home, instead only out to certain nodes; STB sends message to the node that it wants to tune to a channel, then it is sent. This is only being tested in a few markets now, it is unknown if it will be widely deployed or what regulatory hurdles it faces as it not only causes issues with Tivo, but also all Cablecard 1.0 TVs out there.
