To get your EasyCap working with simple programs, you must have the default values set up correctly. When the default values are set up correctly, you can even view EasyCap live video with just Windows explorer.
Look at my complete instructions here
here when reading the next paragraph.
Download and install AMCap (Later we will use AMCap to set the default values correctly) by following the instructions in section "INSTALLING AMCAP:". Plug in the video connections to the EasyCap device and turn on the video signal from the video source, then set the default values correctly by following the instructions in the second paragraph in section "COME BACK HERE FOR THE NEXT USB PORT:". Finally, test your EasyCap with Windows Explorer by following the instructions in section "TESTING ALL USB PORTS WITH WINDOWS EXPLORER:".
