I bought this to expand HDMI inputs on an older Panasonic TV (only two HDMI ports). It worked just fine with an Xbox360, Samsung Blueray (BDH-5900) and a Frontier DVR STB (about 4 years old). I switched over to Spectrum recently and found that the Arris DVR STB that our local Spectrum franchise uses will not work with this switch due to a failed HDCP handshake. Disappointing but all part of the silly copyright arms-race.
Otherwise, this is a decent little 3->1 auto switch and a snap to install.
