Ward - There was an issue previously where a user was experiencing slow frame rates on the iPhone, and the reason behind it was that they had a product called ColorEyes installed:
http://www.integrated-color.com/For whatever reason it was taking over the JPEG compression for their computer, creating exceedingly large images that were taking a long time to transmit from the iCamSource to iCam. Once they disabled ColorEyes, everything worked as expected.
Do you have anything similar installed on your computer? The way we determined this was to connect to their iCamSource with our iCam running in debug mode and see that the image sizes were much larger than they were supposed to be.
If you don't have ColorEyes or any similar product installed, then if you could send an e-mail to support@skjm.com referencing this post then we can continue troubleshooting from there.
