BBC Radio 3 HD outside UK

[angryfokker]

Hello, I'm trying to play/record this stream: http://www.bbc.co.uk/radio3/hd-sound/ , but it's only available in the UK.
I got this address using a UK proxy and it works from my location (outside UK), but it will stop working after a couple of hours (edit: already expired) :

rtmpdump -r "rtmp://213.200.108.77:1935/live" -a "live?_fcs_vhost=cp60703.live.edgefcs.net&auth=daEaFdYdob0aibPbWdCdyb8aXcNbjcfbpbw-bpUrfE-bWG-CqlGEoynNCoFvzK&aifp=v001&slist=Special_Event1_UK@s6485" -f "LNX 11,2,202,235" -W "http://www.bbc.co.uk/emp/revisions/18269_21576_10player.swf" -p "http://www.bbc.co.uk/radio3/hd-sound/" -C O:1 -C O:0 -y "Special_Event1_UK@s6485?auth=daEaFdYdob0aibPbWdCdyb8aXcNbjcfbpbw-bpUrfE-bWG-CqlGEoynNCoFvzK&aifp=v001&slist=Special_Event1_UK@s6485" -v -o bbcradio3hd.flv

Why does the address expire and is there any way to listen to BBC Radio 3 320kbps outside of the UK and without proxy/vpn.

Also, how to find XML file page with BBC Radio 3 320 kbps rtmp address options, like this one?
