I recently had Dish Network installed with a 522 PVR. So far I am very pleased with the 522. My son gave me an old 501 DVR and I am wondering how I could hook it up to another TV. Right now the 522 is set up with TV1 connected to my big screen TV and TV2 is connected to a second TV. Is there any way to spit the input signal to send it to both the 522 and 501? Any help is greatly appreciated.
