Video streaming no longer working in Firefox since v8.04 update

[beerem]

I have recently upgraded to v8.04 and when I try and access a video streaming website I get the message;
The playback of this movie requires a MMSH protocol source plugin which is not installed.
It worked fine with the v7.10 but no longer with v8.04
Any help appreciated.

TIA

Has there been a solution to this? I have the same problem. The error message is "The playback of this movie requires a MMSH protocol source plugin which is not installed."
Thanks for any suggestions!

Is it possible that this problem can be solved by installing a bunch more of gstreamer plugins?

I too have this problem.
Can anyone help?
