Currently, subtitling is only available when you are working with QuickTime-compatible content. You cannot use InqScribe to produce subtitled Windows Media content. This is because InqScribe relies on QuickTime to convert your transcript into a text track and add that track to your movie.

For Windows users, this means that subtitling is not currently available if you are working with content opened using Windows Media Player (e.g. .wmv or .wma). If you can convert your content to a QuickTime-compatible format (e.g. MPEG-4, AVI, MOV), you will be able to make a subtitled QuickTime movie using your source material. If you are working with another media format (not .wmv or .wma) and the Export Subtitled File... menu item is still disabled, make sure that you have selected QuickTime as your preferred media player in the Options dialog.

Mac OS X users can use the free Flip4Mac converter to play .wmv or .wma content in QuickTime, and this should allow you to export subtitled QuickTime movies. However, these movies will contain the original .wmv/.wma content and will not be viewable via Windows Media Player Windows. (Note: You can export QuickTime movies for replay on Windows Media Player using the paid version of Flip4Mac WMV Studio, though this may not export your subtitles. This has not been tested.)
