I know this is probably a very basic and dumb question but I need help from someone out there who knows...I have direct TV in 3 rooms. Two of the rooms are regular and one is HDTV. All this coming from one dish. I got a media center PC and wanted to set it up with it's own separate sattelite box so I took one from one of the other rooms and brought it in next to the HD box. Then I used a regular garden-variety cable splitter to run sattelite to both boxes side by side - one for the media center and one for straight viewing through the HDTV box. Ever since I did that I get "Searching for sattelite signal" or "Channel not available" on several channels. Is there a special kind of splitter I need to do this or is it even do-able??
