Just installed Fedora 17 (64 bit). After installing the good gstreamer plugins, I noticed that I could not play any mkv, webm or mp4 files. Totem complains that the demuxers for each one are missing. However, gst-inspector says that they are installed. I've tried gst123 and it comes up with the same error as well.
Any fixes for this problem?

Oh, I just solved it
I had to delete the .gstreamer-0.10 directory and run gst-inspect to update the registry file inside.
