Query re BBC On Demand Radio

[Prisca]

I don't fully understand how get_iplayer works, even though I have 
managed to learn how to use it - mostly.

I do, however, have a question as to what is likely to happen at the end 
of February when the WMA/AAC streams for on demand radio are turned off. 
Will this have any impact on get_iplayer? I've never really figured out 
where the streams I download actually come from.

Sorry to sound dense, but some of us only manage to get things working 
by trial and error and keeping our fingers crossed. A very simple 
explanation would be much appreciated.

Thanks to everyone who is responsible for get_iplayer. It really is a 
very useful program to have found since the demise of Radio Downloader.

Thanks
Prisca
