We have some web sites in our SharePoint 2010 site collection that need to display SWF files (to play FLV videos). For SharePoint to render the videos, we go to the web application in Central Admin > General Settings > Browser File Handling, and change it to Permissive. This entire SharePoint server is internal (for the intranet).
Is this a safe thing to do? Or should we convert the videos to WMV and not go with Flash? Thank you.
