cat5

There has been this cables in the 4 high corners of my bedroom (old sitting room) since I can remember. They lead back to beside the TV input and where covered in by a blank socket. It says CAT5 E on the sleeve of the cable and looks to be 5 wires inside the cable. Why would they be there ...

My father bought THIS TV without asking me first because it was on sale and it does not support DLNA. I've setup a DLNA server with about 12tb of TV shows Movies etc for mom and dad and now they are mad because it will not work. I am looking for a DLNA Transcoding box and would love some...
