If you are scheduled to present a talk or presentation at STScI that will be webcast, please take a look at our webcast presentation tips and guidelines.
Real Media and Windows Media links (either archived webcasts or live streams) launch the standalone versions of the Real Player and Windows Media Player. In order to view these webcasts you must have the appropriate player application installed on your computer. For optimum performance when viewing, we recommend that you use the latest version of your preferred player. Newer versions often fix performance and compatibility issues and operate more reliably on modern systems.
If you are having trouble viewing Real Media or Windows Media webcasts from STScI, the culprit may be that you are behind a firewall that is not configured to allow RealMedia/Windows Media streaming. If you are receving networking-related error messages (invalid servers, invalid sockets, or transport errors) or cannot view streaming media from any site, the firewall may be bocking your access.
If you think you are having problems viewing webcasts due to a firewall problem, you should contact your network administrator or help desk for assistance.
To play the appropriate media type correctly, your player must be configured to open when you choose to view a specific media file or stream. Selecting fiile types that will automatically open in your preferred player can be done via the player's preference settings.
If you are experiencing problems with display quality, you may want to reduce or disable video acceleration and/or reduce the displayed video quality settings. These settings can also be configured via the player's preference settings.
