Let's say that hypothetically speaking I were to install some packages from http://rpm.livna.org and then rebuild the gstreamer-plugins src.rpm except using a source tarball from gnome instead of the red hat one with removed stuff. And lets this hypothetically resulted in the following plugins: +/usr/lib/gstreamer-0.8/libgstdvdreadsrc.so +/usr/lib/gstreamer-0.8/libgstffmpegcolorspace.so +/usr/lib/gstreamer-0.8/libgstlibfame.so +/usr/lib/gstreamer-0.8/libgstmp1videoparse.so +/usr/lib/gstreamer-0.8/libgstmpeg1systemencode.so +/usr/lib/gstreamer-0.8/libgstmpeg2subt.so +/usr/lib/gstreamer-0.8/libgstmpegaudio.so +/usr/lib/gstreamer-0.8/libgstmpegaudioparse.so +/usr/lib/gstreamer-0.8/libgstmpegstream.so +/usr/lib/gstreamer-0.8/libgstxvid.so but after installing and running gst-register, when trying to play a shoutcast, rhythmbox still pops up a dialog stating: "There is no element present to handle the stream's mime type audio/mpeg." Where would I tell it that it has new gstreamer plugins it can use? I'm tempted to just build rhythmbox from source (rebuild the rpm) but I don't think that is the issue, I've had previous installs of rhythmbox that did simply pick up on the fact that I rebuilt gst-plugins and new capabilities were there. -- Cheap Linux CD's - http://mpeters.us/linux/
