Downloading HD files

[Richard]

I am having problems downloading HD programmes using get_iplayer on 
Ubuntu 11.04.  I am getting the following error message about swf:
RTMPDump v2.3

ERROR: RTMP_HashSWF: couldn't contact swfurl 
http://www.bbc.co.uk/emp/10player.swf?revision=18269_21576 (HTTP error 301)
WARNING: Ignoring SWF size, supply also the hash with --swfhash
Connecting ...
INFO: Connected...
ERROR: HandleCtrl: Ignoring SWFVerification request, use --swfVfy!
Starting download at: 0.000 kB

get_iplayer then downloads 7% of the feed before stopping:
67727.472 kB / 209.52 sec (7.9%)
Caught signal: 13, cleaning up, just a second...
ERROR: WriteN, RTMP send error 32 (42 bytes)
ERROR: RTMP_ReadPacket, failed to read RTMP packet body. len: 96405
67887.512 kB / 209.92 sec (8.0%)
Download may be incomplete (downloaded about 8.00%), try resuming
INFO: Command exit code 2 (raw code = 512)


It then starts the download again and the following occurs:

WARNING: Stream does not start with requested frame, ignoring data...
WARNING: Stream does not start with requested frame, ignoring data...
138005.104 kB / 199.60 sec (7.6%)

138088.859 kB / 199.92 sec (7.6%)
Download may be incomplete (downloaded about 7.60%), try resuming
INFO: Command exit code 2 (raw code = 512)

Then it finally goes into the following loop:
WARNING: Stream does not start with requested frame, ignoring data...
WARNING: Stream does not start with requested frame, ignoring data...
WARNING: Stream does not start with requested frame, ignoring data...

Any ideas?
