gnome 2.22-3 has been released can we PLEASE get this packaged into updates-testing ASAP to 
resolve this issue.

Any update on getting the latest gnome built for F9 testing? The desktop is unuseable as you can't 
select other applications other than rhythmbox and totem. This is a known bug in gnome so we need 
to be building these updates as they are released.

That's a control-center problem. You can modify
/usr/share/gnome-control-center/gnome-default-applications.xml to add media
players by adding the lines:
    <media-player>
      <name>Name of media player</name>
      <executable>executable</executable>
      <command>executable</command>
      <icon-name>icon-name</icon-name>
      <run-in-terminal>false</run-in-terminal>
    </media-player>
for each media player inside the <media-players> section.

Let us know what you added for VLC and Realplayer.

Thanks that's a great help :)

Any idea when the next update for gnome will be pushed to koji and then
updates-testing?

I know 2.22.3 is  July 2 for Stable Release 

Why would that matter, it's not fixed either upstream or downstream.

We need to know what to add to the definitions, otherwise we'll never have them...

Its been added to the VLC package, some new definition is required for the
desktop files for the media players:

edit /usr/share/applications/realplay.desktop

Add this to the mimes...
;x-content/video-vcd;x-content/video-svcd;x-content/video-dvd;x-content/audio-cdda;x-content/audio-player;

Save it and then:

update-desktop-database /usr/share/applications

There was a fix done in vlc update that had new desktop files.

If you're talking about having those applications being registered for
auto-launch in nautilus, then there's nothing that we can do. It's up to the
providers of those packages to add the necessary mime-types.

If you want those media players added to the default applications preferences,
please file a new bug with the additions you made to the
gnome-default-applications.xml file.
