Sunhill,
You should follow the normal instructions for using ActiveX controls in LabVIEW, if Sony has a viewer that can 'play' video then you are set, if not you might need to constantly call a function that will retrieve the image buffer from memory and display it in LabVIEW. For instructions on using ActiveX please check the Development Library, the section called
ActiveX >> General has some information on this.
Otherwise I would advise you to post the question in the LabVIEW Users Group as well.
Good luck!
Nestor.
