The real-time video extension can not capture from my ATI All-In-Wonder card.
This is typically because the incorrect video device is selected for the All-In-Wonder card.
Once in RTV, select the ATI Multimedia Video Driver option from the Video Devices menu. If this driver is not listed, then you will need to download the latest version of ATI's Multimedia video center at http://support.ati.com/faq/mmcenter_availability.html .
For more information, please refer to ATI's web site at www.ati.com.
