Hi Frankie-Capri,
This is proving to be a bit of a difficult problem to track down, especially as we can't get the site working on our own PC's (which don't use Mobile Broadband). I know when we raise this, the first thing our Fault Managers will try to do is ensure the website itself is working fine, but since it's clearly giving us issues too, we can't say that for sure.
The browser we're using should not matter, as the only real requirement here is that the Flash plug-in is installed and working - which it is - but for whatever reason the videos are not rendering or streaming at all. Since we can see more than one system affected (our Mobile Broadband service, as well as our company internet service) this is not a content filtering issue or anything unique to our network - and is much more likely to be something unique to that website or the streaming service they're using.
In this situation I would have to recommend that you contact the webmaster of that website directly to report the issue. Chances are they're already aware of this or similar issues, and may be able to offer an explanation of why it's not working for you.
