DVD Recorder Connections

Just bought a Daytek 950T recorder with a hard drive. I want to connect it to my satellite receiver, TV and sound system. As I currently have it connected the satellite outputs (composite and audio) go into the DVR and then on to the TV and sound system. In this configuration the DVR must always be on. Is it possible to split the signals as they come out of the Satellite receiver so that the TV can be fed directly? That way the DVR wouldn’t always have to be on. If so. can someone make specific equipment recommendations. I was thinking of perhaps some sort of switching system from Radio Shack… Any help or ideas would be greatly appreciated!
