Which receiver do you have now ?
I'm guessing the vip722, since they connected both tv to it.
It has a dual tuner and can run as a single tv box with watch one channel, record another. Or as a two tv box with independent channels and recording.
If you have two remotes, one green at the bottom that is IR, and another that is blue at the bottom that is wireless, that is a 722 receiver.
It has the capability to send svideo ,component,hdmi to the main tv where the box is. If you run it in single mode then you have to watch the same thing on both tv but can run svideo, component, etc to a second tv. In dual tv mode you have to use a coax RF connection and composite+audio for the second tv.
If you want the best picture over the distance and keeping it in HDTV I would run a component cable + audio. It can run several hundred feet and not degrade.
