This was a great idea a few years ago but many devices today no longer have A/V (RCA) output. My Samsung Blu-ray player, for example, only has HDMI output. Also, you can do what this does with a computer or tablet streaming through your network. Finally, Time Warner (and many other TV providers) subscribers can stream its contents directly onto a tablet. I'd buy this for about $39 but $79 is too much.
