What version of Movies2go are you using? The screen capture feature is only available starting in version 2. Proceed as follows: Click the red recording button in the main program screen and pick "Other" as your recording source. There will be another notification and you'll find yourself in the video recording dialog after that. Make sure that "Screen capture" is selected as the video driver. You audio driver should be the sound card, which should be configured to pick up the stereo mix, if you're even interested in the sound of the video you're capturing. Click on the recording button in this dialog again and you will get to proceed to the final step where you position the area to be captured and trigger the actual recording process.
