look for the ATSC connection, that where the over-the-air antenna for digital tv should be connected; and cable connects to the other one.
We just purchased a Samsung 46" LCD HDTV. How do you connect both the Cable TV from the wall & the over the air Atena to the TV or DVD to get both signals? Right now the TV get some over the air digital channels but the signal is not strong b/c no atena is hooked up. Our cable package is real cheap, but not HD. If we can get the HD local channels over the air plus the regular cable channels we would be very happy. Thanks!
