One way to do this would be to create your own .MCL file.
Open up notepad and put something like this in
<application name="BBC Website" url="www.bbc.co.uk" startimage="**** .png image location ****" thumbnailimage="**** .png thumbnail imagepng" description="**** description ****" companyname=" ***** ">
<capabilitiesrequired directx="false" audio="false" video="false" intensiverendering="false" console="false" cdburning="false" />
</application>
Where I've put in ***'s in you will have to put a link/url to a .png image so this comes up in your MCE menus. Also change the references to the BBC webiste

you could also play around with the other bits but for an IE link theres no need.
Once you have done this save it as a .MCL file to the following location.
ACCESSORIES -> MEDIA CENTER -> MEDIA CENTER PROGRAMMES ->
Once you have done this it will appear in 'More Programmes'
any probs let me know.
