I've installed Flirc and created a Harmony activity to include Flirc media center, my TV and my audio source. Do I still need the old USB IR receiver which I was previously using to permit the Harmony remote to communicate with the computer? If I remove the old IR receiver will the Harmony communicate with the PC via Flirc to activate my other Harmony activities (e.g. watch a DVD, listen to music)? Or do I need to make device changes in those activities? Confused....
