Review of the DirecTV TiVo "replacement"

As you probably know, DTV ended their deal with TiVo and their offer of a TiVo unit for their subscribers, and have now developed their own ripoff. I say "ripoff" because it sure looks like a close copy in the review and screenshots this guy has up here: A Review of the R15.

Admittedly, there are a couple of things in here that I consider improvements, things we got wrong that haven't yet (AFAIK) been fixed in the TiVo UI. And they do offer the often-requested disk usage measure :-) But they have outright copied much of the UI including a lot of the TiVo UI wordings, while losing the friendly look&feel and sound effects. I imagine there are grounds for lawsuit, especially if it's true that they copied the fast-forward autorewind correction, for which I am quite sure TiVo has a patent.
