This is for TV's with A/V inputs. This will also work with HDTV's and all TV's with A/V inputs. with just composite video inputs to get a tuner working on it or if the tuner on the TV is not working that good. This also works with TV's with RF modulators. Hooking up a digital converter box is just as easy as hooking up a DVD player or VCR. The A/V feature is great for TV's and video capture cards without RF connections.
