Query: Did not work with my DirecTV HD DVR!

I have a LCD TV with only one HDMI input so I purchased this product to connect my DVD upconvert player and HD DVR into one input without switching cables every time I would switch from one to the other. The auto switching worked great! It did what it says, when you turn on your source, it switched to it automatically. But I could not get a picture from my DirecTV HD DVR! Sound-yes! Picture-no! I also had to keep changing the resolution back to 1080i on my DVD upconvert player because for some reason it would switch back to 480i when using this auto switch. I would not recommend this product!!
