I don't think it's possible. For years now the movie industry has put pressure on anyone making a digital interface that has the bandwidth for HDTV to include Digital Rights Management into the interface electronics. Firewire has this for sure.
USB-2 doesn't, but if the device storing the video has DV or DVD licensing, it's not allowed to carry the video as a term of the license.
I'm pretty sure the DVR satellite box has similar restrictions.
