Thanks everybody for all the excellent advice. Sound Juicer is now ripping to mp3 files on the FC4 machine. Just for the archive, here's an updated version of my notes:- <MP3NOTES> 1) Put the following into /etc/yum.repos.d/Freshrpms.repo (might need to change the first line to reflect the FC issue number:- [freshrpms-fc-3] name=Fedora Project $releasever - $basearch - freshrpms baseurl=http://ayo.freshrpms.net/fedora/linux/$releasever/$basearch/freshrpms 2) Import the GPG key:- rpm --import http://svn.rpmforge.net/svn/trunk/rpms/yum/RPM-GPG-KEY-freshrpms 3) Install the plugins:- yum install gstreamer-plugins-extra-audio 4) Add an mp3 profile (if required - check first!) Extract from email reply from the Fedora Core list:- <extract> If you need to store tracks in the MP3 format (for example, because your portable music player only supports MP3 and not Ogg Vorbis), you will need to create a new profile. To do this:- run gnome-audio-profiles-properties press New and name it MP3. Then press Edit and set GStreamer Pipeline to audio/x-raw-int,rate=44100,channels=2 ! lame name=enc or maybe audio/x-raw-int,rate=44100,channels=2 ! lame name=enc preset=1002 the File Extenstion to mp3 and check Active. Then start Sound Juicer and select the MP3 format. </extract> 5) Make sure all the required gstreamer stuff is installed:- [dave@boss ~]$ rpm -qa | grep gstreamer gstreamer-0.8.7-4.FC3.0 gstreamer-plugins-0.8.5-1 gstreamer-plugins-extra-audio-0.8.6-2.1.fc3.fr [dave@boss ~]$ Now it should work! Notes on setting up the gstreamer profiles:- http://paul.frields.org/?page_id=524 Also might need to use yum install xmms-mp3 to get this working too. </MP3NOTES> -- Registered Linux user number 393408 I use and recommend the email service at 1 & 1 For domain registration, email and web hosting please visit: http://oneandone.co.uk/xml/init?k_id=6389763
