Comment 14 for bug 432701

From here http://www.ubuntu.com/community/ubuntustory/components:
The main distribution component contains applications that are free software, can freely be redistributed and are fully supported by the Ubuntu team. This includes the most popular and most reliable open source applications available, much of which is installed by default when you install Ubuntu.

The package libxine1-ffmpeg is in main, so it can become a strong dependency of libxine1 which will resolve this usability bug.

If you think libxine1-ffmpeg should not be in the main component (which could be true) then you need to file a new bug in order to have it moved to restricted, but we need an official/"legal" answer to this.

Until then the bug is valid and with known solution.
