WR - correct, if you look back through this thread, the original stream is quiet old. The wiki page you refer to was setup around then to make it easier (it still just a workaround, not true LMCE media), and my provider, Internode have a few dozen Internet Radio sites repeated to their customers.
The question of TV is somewhat stickier, as most of these providers are not true continuous channel streamers. They are fixed blocks of content you can call upon. Moreover, they are usually embedded within their own web UI that forms part of the experience, which makes integration with LMCE a messy process at best...
