Flash® Video (FLV) is a file format used to deliver video over the Internet using Adobe® Flash Player. FLV video files are loaded and played inside existing Flash movies; thus Adobe Flash Player requires them to be physically available on the hard disk.
IE Browser publications now have native support for Flash Video files: they should play normally. See this option if it does not work.
this feature is still experimental in HTML Executable 3.3.
Very large video files may not be supported (in fact video files may not play on computers with restrictions on the space dedicated to the Temporary Internet Files folder); please also keep in mind that video files must be unpacked to the hard disk in order to be played.
