Problems downloading Rise Of The Continents

[By Tor]

Hi,

Having specific problems downloading episodes 3 and 4 of Rise of The Continents

http://www.bbc.co.uk/iplayer/episode/b0368kb2/Rise_of_the_Continents_The_Americas/

and

http://www.bbc.co.uk/iplayer/episode/b036ks6f/Rise_of_the_Continents_Eurasia/



Seems to start OK:

but then it just stays like this. Have tried a number of other
programmes on the iPlayer which seem to download OK.

Any idea why these particular ones are proving so troublesome?

Many thanks for advice
