You may have a previous partial download for that programme in your 
output directory.  Delete the <whatever>partial<whatever>.flv file and 
try again.  get_iplayer invokes rtmpdump so that it will attempt to 
resume a download if it finds a partially-downloaded programme, but it 
often doesn't work, for any number of reasons, so you need to start over.
