I am marking this bug as confirmed as I have tested this myself. The issue gets worse in karmic which simply crashes instead of proposing plugins.

The link to test is:
http://bloomberg.com/avp/avp.htm?clipSRC=LiveBTV

This uses the totem plugin, and requires a package that can decode proprietary microsoft protocols. On a base install, going to this page will make totem pop up, proposing to search for packages that can read this stream. It is not able to find any packages to fit this need.

gstreamer0.10-plugins-ffmpeg - black screen, no proposal of plugins presented, totem plugin shows "Playing 0:00 (Streaming)"

gstreamer0.10-plugins-bad - proposes to search for plugins, which recommends gstreamer0.10-plugins-ugly

gstreamer0.10-plugins-ugly - once all three installed, I got a second of video then I was proposed more plugins, which failed because there was no package found for Windows Media Speech decoder.

w32codecs/w64codecs (medibuntu) - saw video for a second, makes no difference Windows Media Speech decoder is still needed.

Looking for bugs of people who have experienced the same thing, I found Bug #298189 and Bug #301120 which also explain the same issue. Looking at the ubuntuforums link you provided. I got the idea to try it in VLC. From the totem plugin window menu, I select "Copy" which copies the source of the video, which in this case was:

mms://a627.l2479952251.c24799.g.lm.akamaistream.net/D/627/24799/v0001/reflector:52251

I pasted this into vlc's Open > Network Stream bar, which gave me the video, but no audio. I also got the error:

No suitable decoder module: VLC does not support the audio or video format "wmas". Unfortunately there is no way for you to fix this.

So in fact totem is not failing, the plugins in ubuntu repositories are enough for the video, but since it can't decode the audio the totem plugin stops there. Whats missing is libdmo_plugin.so which is the WMA2/WMAS decoder module.

So in conclusion, this bug is a request to include the WMA2/WMAS audio codecs to the gstreamer plugin packs and to vlc. If there are any issues with doing this please comment on this bug.
