Oh I see. Hopefully the beeb's streams will stay the same for a while. Have a look at the streams available by selecting one of the programmes in this list. I think (but not totally sure) they're client-independent.

Slightly offtopic: Has anyone had any problems playing the mp4 files downloaded with get_iplayer? I assume they're h264? I keep getting the Unable to play media, bad codec message. Thought I had all available codecs installed? And the media player can see + get length of these files... very strange.
