Hi there I am considering getting a Logitech Harmony 555 (or even the 525 maybe) and my setup is as follows: Panasonic TX-32LXD700 LCD TV Logitech Z-5500 surround sound speakers What I want to know.... 1) Is the remote compatible with the TV? 2) When using the Logitech Speakers I need to turn down the volume on the TV fully - would there be a way of getting the Harmony remote to automatically do this with a single button press - so perhaps I could set up a macro called 'watch TV thru Z5500 Speakers' so that when activated, the Harmony turns the TV volume ALL the way down and then lets me control the Z5500 speaker volume from the Harmony remote. 3)Can the Harmony remote control the speaker system volume in the same way as their dedicated remote.....ie. sub volume, surround volume etc. ? Thanks!
