Any World Service listeners noticed a problem over the last month or too with the stream? I get a kind of background, rhythmic clicking noise. It's only with the World Service (no other BBC streams or from any other station), and also doesn't happen with the iplayer stream on the BBC website, unless I click on "Play in Real Player or Windows Media Player", in which case I hear the clicking. Also still happens if I'm directly connected to the internet with ethernet, with wireless switched off.
I'm outside the UK, so not sure if that's relevant – from what I remember there are different streams for people listening abroad.
