Nothing to do with the user agent.  Last week the chart show playlist 
was incorrect, pointing get_iplayer to a "bbc_radio_one_video_live" 
service that didn't exist.  It was fixed this week, now pointing to a 
"bbc_radio_one_video" service that returns the necessary stream 
descriptors.  However, since you are trying to stream your programme to 
VLC rather than record it to disk, get_iplayer stops if the stream isn't 
available from the first CDN it connects with 
(NetStream.Play.StreamNotFound above).  If you look at the download log 
Vangelis posted, you'll see that his first attempt (flashvhigh1) fails 
and get_iplayer rolls over to the other CDN (flashvhigh2).  That 
rollover doesn't occur when you're streaming rather than recording.  The 
workaround is to change --modes=best to --modes=flashvhigh2 to access a 
specific CDN when attempting to stream the programme.  If that returns a 
similar error, switch to --modes=flashvhigh1, flipping back and forth if 
necessary until you get a connection.  That is because the "1" and "2" 
may refer to different CDNs for different invocations of get_iplayer 
(the BBC metadata is generated dynamically).
