I don't know what year or features your system has and what outputs you need from the disc player. I needed to replace an older DVD player, so I went to Best Buy and purchased a BluRay player with a was brick, discarded the wall brick and went with a 12volt cable. The player I bought has only one HDMI output and so I bought a Splitter and cable for the rear TV. Often the DGKs are in back and want to watch the same thing we have playing up from, ergo the splitter and cable. There is a greater selection of players that use 120 volt but the simple one works great for us.
