Description of problem: I play a movie with totem (such as an ogg/theora file like http://www.redhat.com/v/magazine/ogg/inevitable.ogg) and the sound plays fine, but instead of the video it displays only a black rectangle. I can make video appear by changing the /system/gstreamer/0.8/default/videosink gconf key from "xvimagesink" to "xvimagesink name=xvimagesink0" even though xvimagesink0 should be the default. Perhaps this is related to Bug 151579 Version-Release number of selected component (if applicable): totem-1.0.2-1 gstreamer-0.8.10-1 gstreamer-plugins-0.8.8-6 One shouldn't have to use gconf-editor to play movies with totem. It should work out of the box.
Can you reproduce this in FC5? A bug with playing ogg/theora video was fixed in totem-1.3.1. This certainly WORKSFORME without any gconf changes.
This is not only fixed, but not even really relevent anymore, since as of gst-0.10.x, we have the autovideosink and so which sets up xvimagesink (or whatever) correctly. I'm closing this bug.
