I'm using FC3 with Gnome, with all updates automatically (using the yum.conf suggested by fedorafaq.org). When I double-click on an ogg file, XMMS launches and plays the file. If I right-click and choose "audio player" (which I think means rhythmbox) instead of XMMS, it also launches successfully and plays the file. On the other hand, if I try either of the same tasks with an mp3 file, the apps launch fine but do not begin playing the file. If I then go to File--Open or File--Play File, I can play the file. In other words, both players can launch correctly, and both players can play mp3 files, but neither will launch AND play the file. Any thoughts? Obviously I can work around this but I'm going through a lot of digitizing lately and it would be great to fix this. Thanks, Matt
