Another dull RealMedia question (sorry)

(Feisty herd-3 - live environment)

I've read through many support tickets about RealMedia and was hoping for a reasonably clean way to get things moving.

I've followed the RestrictedFormats wikipage, and specifically

https://help.ubuntu.com/community/RestrictedFormats/WindowsCodecs

so I now have /usr/lib/codecs and /usr/lib/win32 populated with 30MB of DLLs and .so's

I also have every gstreamer-plugin package installed:

ii gstreamer0.10-pitfdll 0.9.1.1+cvs20060515-1
ii gstreamer0.10-ffmpeg 0.10.2-0ubuntu4
ii gstreamer0.10-plugins-bad 0.10.4-1ubuntu1
ii gstreamer0.10-plugins-bad-multiverse 0.10.4-3
ii gstreamer0.10-plugins-base 0.10.11cvs20070110-0ubuntu5
ii gstreamer0.10-plugins-base-apps 0.10.11cvs20070110-0ubuntu5
ii gstreamer0.10-plugins-good 0.10.5-1ubuntu2
ii gstreamer0.10-plugins-ugly 0.10.5-0ubuntu2
ii gstreamer0.10-plugins-ugly-multiverse 0.10.5-2

In addition, I have killed and recreated my gstreamer cache:

# rm -rf ~/.gstreamer-0.10
# gst-inspect-0.10

However, totem /still/ refuses to play RealMedia content..

ubuntu@ubuntu:~$ totem --debug rtsp://rmgeo.bbc.net.uk/news/media_acl/mps/fix/news/video/78000/bb/78213_16x9_bb.rm

'Unsupported Transport' would seem that it doesn't know about rtsp - how can I verify and remedy this?

I would very much prefer to not install mplayer / totem-xine / RealPlayer GOLD etc. !
