'lo, to start: thanks for building the plugin.. it works for most of the commands on my Viera VT50 (plasma) TV. What puzzles me though, is that only some of the commands work.. e.g. https://address/json.htm?type=command&param=panasonicmediacommand&idx=723&action=inputtv works, where https://address ...
