Thanks for the replies. I've included some screenshots that should help.
The large blob at the top of RedTrak.jpg is definitely the result of the darkness seen at the top of RedCapt.jpg. It does appear as soon as the tracking starts and stays as long as the cam is pointing as such. If I point the camera to a dark enough part of the room it will sometimes fill the whole screen. Other colors, namely blue, do track properly, so it is just red. I've tried Auto White Balance on and off but not much difference. The other "general" registers are disabled. RedCapt2 shows the same red object against a different background and as you can see I get other long horizontal blobs that extend the width of the screen. I am, of course, able to work around this by ignoring blobs that extend the width of the image but if there is something I could do that would be great. The power supply, BTW is not a 9V (I deemed those worthless long ago). I use a 9V wall wart (500mA) or a 7.2V AA battery pack both with same results so I'm fairly certain it is not the power supply.
