I would like to use TImageEnMView to view thumbnails, however I can't make it display video thumbs like TImageEnFolderMView does. It displays the registered file type icon instead. See image attached; test application with each component. The only source is below. IEGlobalSettings().MViewExplorerThumbnailExts includes .MP4 (both files are this type).
ImageEn is using the Explorer Shell Extension to retrieve thumbnails for those video types, because they are small, they are not used if the StoreType is ietNormal (full size images).
