Oh yeah, I had to buy one of these (I called it the HDCP defeater) because my receiver was otherwise unable to forward the negotiation between the Roku and the TV fast enough. I would turn on the TV and the screen would blink on and off for several minutes before the HDCP handshake managed to win the race. In theory those devices might be defeated with newer versions of the protocol, but that part that drives the matrix of pixels can never be encrypted until you have DRM built directly into your eyeballs.
