Anybody please help me here? I am looking to buy a Panasonic DMR EX 77EB DVD recorder to replace my Panasonic SA-HT870. Can I connect the DMR EX 77EB dvd recorder to my current surround sound which is the Panasonic SC-HT870. The current player SA-HT870 is connected to the SURROUND SYSTEM SC-HT870 BY A SYSTEM CABLE (K1HA25HA0001). Any advice would be great. As the surround sound is fantastic I do not wish to replace it. The current dvd player works fine, just want a recorder. Thanks
