Looping
Playback
MCIWnd
supports playback as a continuous loop. You can play the content of a file or
device repeatedly as a loop by using the MCIWndSetRepeat1ZO70U macro in combination with
the Play button on the toolbar. The video playback device, MCIAVI,
supports playback loops. To determine if continuous playback has been
activated, use the MCIWndGetRepeatAX0EG_ macro.
