Do you have Ubuntu and when playing mp3 files you can't control the seek bar cause the file length is unknown ?
If yes, then this post is for you.

To solve this you have to install the package called:

ubuntu-restricted-extras

1.Go to System > Administration > Synaptic Package Manager
2.In the search area search for "ubuntu restricted".
3.Select the package named ubuntu restricted extras and install it.
4.Congratulations!

this worked with me on Totem Movie Player.

When I installed fedora 12 today .. i rebooted for the first time and it went OK

On the second reboot it didn't show the Login GUI. Instead it showed a black screen with something about SELinux and with options of enforcing and permissive :D .. i actually don't remember it exactly cause i was in a hurry and needed a working system .. i had nothing to cry about in the newly installed system , except for the time i spent installing it , so i reinstalled it and rebooted for the first time and then logged in and searched for a solution before i make the second reboot .
I found this page which was very useful ..  just disabled SELinux .. and tahnks to Falko Timme my fedora is OK now.
I hope it doesn't crash soon  :D
