Hi, This will depend on a few factors: 1) Ensure both computers have multicast connectivity (or use a bridge). 2) Ensure that you are using the same venue for both. 3) If the sending computer is slow i.e. the sending frame-rate is below 1 fps, you might need to wait a bit at the receiver for enough data to get through for a single frame (this is a JPEG video requirement).
