Ernest over at Corante has a great story on a new Maxtor DVR product: "Crippled External Hard Drive for DVRs." Turns out that Maxtor is producing a new external USB/firewire backup drive for DVR set-top boxes, but it won't be sold to customers but instead only to cable and satellite companies. Since you won't actually own the device, you won't have any rights to get at the data inside the drives, apart from your set-top box.
Sounds totally brain-dead and protectionist to me. Honest people that pay their cable bill are going to want a way to load the shows onto their laptops for travel or their PC for playback in other rooms and when they find out they can't, I'm sure there will be a PR disaster on the hands of any cable or satellite company that chooses to adopt these devices.
