Video should be set down to 800x600 but it could be the codex isn't compatible. If you want to send the camera into our service center we can try to make it work at no charge and send it back. (Just put in letter that Johnny Electronic asked you to send in) It would give us a chance to test it and we will get it setup, if it is at all compatible.
You might see if you can interest Furuno Germany in the testing. I am currently working with an IRIS camera that works well that the settings look very similar to your camera. I should have a baseline you can compare to in the next few days. I will send you a direct e-mail with the baseline as soon as I finish it.
