Hi thanks for all this support: I'm another non-tech refugee from radio downloader. So only interested in audio. With the help of these excellent guides, I installed GetiPlayer which is working fine but after setting a conversion default for mp3, it seems to transcode only to 128kpbs although the data suggests that the BBC Proms are streamed at 325kbps. Here is the data:
Stream mapping:
Stream #0:0 -> #0:0 (aac -> libmp3lame)
size= 82830kB time=01:28:21.08 bitrate= 128.0kbits/s

the --radiomode= function seems only to affect the original download. Can the transcode rate be set or should I do my own transcoding with RealPlayer (shudder)?

Radio 3 is a special case where MP3 encoding is concerned. By default, the AAC to MP3 conversion with produces 128kbps constant bit rate files. That is fine for speech programmes and most music programmes from other stations. If you wish to convert the higher-quality 320kbps music programmes from Radio 3, add the option with a value of 0 (it can range from 0 to 9, with 0 being the best, target bit rate 245kbps). That will produce better conversions using variable bit rate encoding. For example:
