I deleted my preferences file - re-created it and have a Tele problem

[Clive]

I stupidly cleared my preferences file, tried to recreate it - radio is 
fine but tele fails with what appears to be an rtmpdump error. The 
opening section of get_iplayer is as follows:

get_iplayer "a word" --type=tv -g
