For these cameras, which profiles worked for:
In the multi-cam view, the lowest bandwidth option is used (JPEG/MJPEG) while in the single-cam view the highest quality/bandwidth option is used (RTSP) to connect to your camera. That's assuming you have a RTSP profile selected for the camera. If just JPEG/MJPEG then MJPEG is used in the single-cam view and JPEG in the multi-cam view for the camera.
Example: If you find that MJPEG works fine for the camera(s) you could disable JPEG and RTSP to force MobiLinc to only use MJPEG for all views of the camera.
If you are still having trouble getting these two cameras to work reliably, please send us your external IP, port, and a username/password we can use to connect to your cameras to investigate. Please send to: firstname.lastname@example.org
