CMD Line Radio downloads have stopped working with Windows

[Chris]

On both my computers (Windows XP) one running 2.85, the other 2.86 I am 
no longer able to download radio programmes from the domestic network.
This seems to have happened since the weekend
I normally work in command line mode using a string of index addresses 
finishing with the mp3 conversion parameter (--aactomp3)
System is suggesting that I use --modes=wma and I've tried this but the 
download performance seems to be diabolical ..30mins to d/l Radio 4's 
"iPM" < 21MB.
Have the BBC done something when they introduced the "new" iPlayer.
