I got my X1 at launch and connected my cable receiver "Smart CX70 DVR" via HDMI with my X1. Watching TV works fine, but my X! doesn't even recognize my receiver.
Just the "TV" and "Audio Receiver"-options are listed, but nothing like "cable receiver", "video receiver" or "set top box".
Can anyone help me? Is it not recognized, because the receiver isn't supported yet?
