Record iPlayer video from current position?

[team mate]

Hi!

I was wondering if there's a possibility to record an iPlayer video from a current position, e.g.

http://www.bbc.co.uk/i/b01m1l2q/?t=1h03m50s

I've looked though get_iplayer and rtmpdump "manuals", but can't find an option. Even having a fiddle with rtmpdump and various settings wasn't successful.

Does anyone have a solution?
Thanks in advance

use --start 3830

rtmpdump -r "rtmp://bbcmedia.fcod.llnwd.net:1935/a1414/e3" -a "a1414/e3?

Thank you so much!

Stupid question: how did you get the 3830? How would I figure that out myself?


edit: duh, it's seconds...
