Users can only upload .flv (Flash file format) video files.
For users who have content in other formats, there are a number of converters out there for many different operating systems that will convert almost any format into an flv file.
GoGogh Course presentations will run on Linux, but users must first install Moonlight, the Linux version of Microsoft's Silverlight.
More information on Moonlight can be found here: http://www.mono-project.com/Moonlight
If you are using IE8 and you are not able to launch a course it will most likely be due to setting or plug-ins that aren't working. This is most often fixed by clicking tools, internet options, advanced, and reset. You will then need to close out of IE and reopen.
The GoGogh Radio works using Flash. Make sure your browser has a working Flash Plugin. You can download Flash for free from http://get.adobe.com/flashplayer/
