The above video should play on Windows Media Player.
The lights/indicators on the tuner did not show up well in the video,
especially the red ones, they almost look white;
I am an audio guy, not video; I have no hardware or software to process video.
I also did not do the video in .avi format because, in my extremely limited experience,
.avi uses a lot more file space, which becomes a problem for uploads, downloads, etc.
The "TUNE" red light is not lit in the photo because it is touch sensitive
and lights up while you are turning the tuning knob.
Some of the photos may have been downsized, email me if you need more detail.
