The BBC News website was set up before Adobe's Flash Video became the de facto web standard for video play it is today. As a result, the videos are available in two formats: Windows Media Player and Real Player. Now, Windows Media Player isn't available for Linux, but Real Player is, so we have to use that. However, it doesn't seem to include a proper plugin for Firefox so it won't display in the browser, and when you try opening it in the standalone player, it plays without sound, which is extremely annoying!
But, with a little bit of work, you can get it working. First of all, you need to install Real Player 10. If you've added Medibuntu as shown in my previous post, it can be installed from there. I actually installed it using Linspire's CNR service (I promise I'll show you how to set that up sometime soon!), but it doesn't matter where you get it form. To install it from Medibuntu, open a terminal and enter the following:
sudo apt-get install realplay
As usual, apt-get will download and install Real Player 10.
Now, you need to add the Firefox extension MediaPlayerConnectivity (unfortunately you need to be using Firefox to be able to get this working, although it's possible Flock might work as some extensions work with it). Grab this from the link and wait for Firefox to install it, then restart. You'll go through a very quick wizard - just make sure it detects Real Player and sets it as the default application for RealMedia, Windows Media, QuickTime etc.
Once that's done, head to the BBC News website (or whatever other website you wish to view the video content on). Once you find a video you want to watch, DON'T left-click on it as usual. Right-click, and select either Open in New Window or Open in New Tab. The reason is that you need this to open in a full window to work properly.
It should now look something like this:

Look for the "+" sign in the top-right hand corner of the player's frame and click on it to open the MediaPlayerConnectivity toolbar (or go to View>Sidebar>MediaPlayerConnectivity in Firefox). This sidebar will give details of all media links on the page. Just click on the one you want, and it should now open in Real Player, with sound and everything! You may need to refresh the page to find it, but I have found it generally works pretty well.
I know, it's a bit fiddly, but it's good to finally be able to watch news articles on my favourite OS!
