Thanks JCA. Ok so this is odd, because your command line is not all that 
different from my ones that did not work, I've diagnosed the problem as 
being to do with the --modes setting. [See working and not working 
commands below.]

Please note I am using yesterday's (2012-07-28) git upload: 
get_iplayer-c3aafce

I have no problems streaming the olympic streams linked on this page:

http://www.bbc.co.uk/sport/olympics/2012/live-video

They play at: H264, 1280x720, FR: 25

Example command line:

./get_iplayer --stream --url 
"http://www.bbc.co.uk/sport/olympics/2012/live-video/p00w2tks" | vlc -

For the main BBC streaming channels, here are some working and not 
working commands:

Working (based on JCA's example):
./get_iplayer --stream --modes=flashvhigh2,flashhigh2,flashstd2 
--type=livetv "BBC One" --player="vlc -"
Plays at: H264, 688x384, FR: 25

Not Working:
./get_iplayer --stream --modes=best --type=livetv "BBC One" --player="vlc -"
main stream error: cannot pre fill buffer

Not Working:
./get_iplayer --stream 
--modes=flashvhigh1,flashvhigh2,flashhigh1,flashhigh2,flashstd1,flashstd2 --type=livetv 
"BBC One" | vlc -
main stream error: cannot pre fill buffer

Not Working:
./get_iplayer --stream 
--modes=flashhigh1,flashhigh2,flashlow1,flashlow2, 
flashstd1,flashstd2,flashvhigh1,flashvhigh2,rtsphigh1,rtsplow1,rtspstd1,rtspvhigh1 
--type=livetv "BBC One" | vlc -
main stream error: cannot pre fill buffer

Working With Errors:
./get_iplayer --stream --modes=flashvhigh2 --type=livetv "BBC One" | vlc -
Plays at: H264, 688x384, FR: 25
Repeated Error: number of reference frames exceeds max (probably corrupt 
input), discarding one

Working With Errors:
./get_iplayer --stream --modes=flashhigh2 --type=livetv "BBC One" | vlc -
Plays at: H264, 640x360, FR: 25
Repeated Error: number of reference frames exceeds max (probably corrupt 
input), discarding one

Working With Errors:
./get_iplayer --stream --modes=flashstd2 --type=livetv "BBC One" | vlc -
Plays at: H264, 640x360, FR: 25
Repeated Error: number of reference frames exceeds max (probably corrupt 
input), discarding one

I can not stream at a higher resolution than 688x384 with the BBC live 
channels, although the Olympic streams work fine playing at 1280x720. 
This is despite the fact that the info command:

./get_iplayer --info 80003

Gives me:

modes: default: 
flashhigh1,flashhigh2,flashlow1,flashlow2,flashstd1,flashstd2,flashvhigh1,flashvhigh2,rtsphigh1,rtsplow1,rtspstd1,rtspvhigh1

Anyone got any ideas what is going on and how I can get this working?

Thanks all.
