We can not follow instructions to install DVR to HD tv. It came with some many cables. Does it make any difference what HDMI outlet I connect it too on my Samsung TV. do I connect the B-band converter too. what about the three colored cables, do I connect them too. Can I still use my CD player and have it connected to me TV. It says not to open the card envelop. Why? It looks like DVR won't work without it.
