I've not tried this in a while, but this does not look good. The 
media type for an ogg file is application/ogg. audio/x-vorbis refers to 
the demuxed vorbis packet stream inside. The way normal gst-0.10 works 
is that there's an oggdemux component that parses the application/ogg 
container and uses audio/x-vorbis video/x-theora etc. to autoconnect 
with the proper decoders. However (last I looked) the tremor component 
includes an ogg parser (which is why you can feed it directly from 
filesrc) so you probably want to be registering the application/ogg 
media type, not the audio/x-vorbis one for tremor.
