Lyndel, you are right about my denon receiver module, it's was designed to be used while operating a Denon CD/DVD/BD player/changer with my denon player module. However almost all commands/parsing is in the code and are easy to call (receiver1.Command.ZoneMain.VideoSource.VCR1), but there is no GUI for it yet. The next version will have a receiver GUI and it will increase in functionality over the next versions. However I've got no idea when I get to it, and I'm still not sure if I'm going to include TSU9400 GUI. Another project is eating up my time and I'm still thinkering with the idea to provide full readable source.
