The only things on are the HTPC, AV receiver, TV. It does seem to change depending on whether the room lights are on. I've just recorded all my commands at sensitivity levels of 1,2,3 all in my Devonshire Fudge Tin. Now trying it in different USB ports in the PC, also seems to be worst when I plug it into the front port.
Out of interest Chris, what are your Harmony settings. At the moment mine are all 200ms and the responding too much to commands one is set at 0.
And could the interkey delay be of any use? Currently set at 6 but have tried it at 2, can't quite remember the difference if any.
Also am I correct in assuming that the sensitivity level of 3 is the least sensitive, only assume this because when I tried 0 each command could be recorded several times each with a different code from the same key, leading me to believe that the Flirc was picking up a lot of noise.
Can upload my fcfg files if that helps at all. I'm using the Samsung TV profile recommended, tried the Panasonic one but as I have a Panasonic TV that didn't work so well, also tried the Sky HD PVR one that someone else recommended but it was very sluggish indeed.
I can't really think of anything else to try now, and I can't quite get my head around why the Flirc just keeps repeating the same command over and over until I either remove it or use another button. It's like it gets stuck in an endless loop.
I had problems with Phantom commands before but managed to sort that one out with the Fudge tin.
