hi, I have a strange problem. I'm using FC5 and had mplayer for video playback. after installing Totm-xine from one of the online repositories my mplayer stopped working.
Now whenever i rum gmplayer or mplayer command from a terminal it gives me following error"

gmplayer: error while loading shared libraries: /usr/lib/libavformat.so.50: cannot restore segment prot after reloc: Permission denied

When I checked the /usr/lib/libavformat.so.50 file it says that its a link and it doesn't allow me to set permissions for it.
plz help.

Were you trying to change permissions as root? If root owns it, only root can change permissions.

The command 'file /usr/lib/libavformat.so.50' will tell you what type of file this is. ( without the quotes ). If it is a link, run as root the command 'locate libavformat.so.50' without the quotes. You may get a message about the data base being more than 8 days old. Run the command as root 'updatedb' ( no quotes ). That will take a few minutes the first time. Then re-run the locate command. The system should list the path to all files called libavformat.so.50. Go to what ever path you find and adjust the permissions with chmod.
