Recently got the Panasonic DMR-E30 and so far have been pretty happy with it but I have a question that maybe someone out there can answer. Can this unit record 5.1 surround sound with out some sort of 5.1 input source. I have a sat. dish with 5.1 output. Have tried it through the regular RCA inputs but the signal just isn't the same. There is no optical input for this. Next question is there a recorder out there that will record 5.1 digital surround sound from a digital sat dish
