Get_Iplayer not recognising existence of HD

[Sara]

It doesn't seem to be recognising the existence of HD?

Normal link:
www.bbc.co.uk/iplayer/episode/b01kkp65/Holby_City_Series_14_Stepping_up_to_the_Plate/
HD link:
www.bbc.co.uk/iplayer/episode/b01kkp65/hd/Holby_City_Series_14_Stepping_up_to_the_Plate/
(DEFINITELY exists)

But Get_Iplayer:
C:\PROGS\get_iplayer>get_iplayer --pid b01kkp65 --modes flashhd
