Home > Movie doesn't open
In the dark ?
Try opening the same movie with QuickTime Player.
If you cannot open it either, it means that your system cannot decode the media data. It's probably lacking a codec or an importer component.
Most common cases are: MPEG-2, DivX, WMV, Flash
See List of recommended codecs to find a solution.
If you can open it with QuickTime Player but not with SimpleMovieX, it's probably a problem of Digital Rights Management (DRM). Indeed, SimpleMovieX needs to write a copy of the movie to be able to open it. If the movie is protected by a DRM scheme, this is not possible.
Future versions of SimpleMovieX will try to open protected files as "read-only".
Still in the dark ?
Maybe the movie file is damaged? Most damaged files can be repaired, but that's a complex task that requires a technician.
Treasured is a free application also developed by Aero Quartet, that provides a diagnostic and a preview of damaged files.
