Do i need to convert a WMV file? Presentations2Go Support September 14, 2015 11:49 Follow Do i always need to convert wmv files when creating a new richmedia recording? Have more questions? Submit a request Comments Presentations2Go Support March 29, 2011 18:57 The Presentations 2Go Silverlight player does not support all windows media codecs. E.g. WMV9 Screen and WMV9 Image are not supported. Also high bandwidth videos cause problems at certain end-users. We suggest to convert your WMV file to a save format in case you run into trouble.
