It looks like the r= and g= tokens change with time. I will check this more rigorously, later.

Saying that, I had failures with -

The World's Most Beautiful Sites S2 Ep37 - El Escorial Monastery

--- 2 attempts, same URL (r, g as follows)

'http://sbsauvod-f.akamaihd.net/SBS_Production/managed/2012/04/2222341564_,128,512,1000,1500,K.mp4.csmil/bitrate=2?v=2.5.14&fp=WIN%2011,1,102,55&r=MADHF&g= XDFCPGQCWAKW'

--- a few minutes later, used FF/FG to get URL, tried again

'http://sbsauvod-f.akamaihd.net/SBS_Production/managed/2012/04/2222341564_,128,512,1000,1500,K.mp4.csmil/bitrate=2?v=2.5.14&fp=WIN%2011,1,102,55&r=LNQSO&g= BXINBBBTSGRJ'
---

(that failed, too - unusual, as several downloads using this method with VLC to do the actual download have all worked, albeit very slowly)

(left off seek when using VLC)

Note changed r and g values, again
(bitrate=3 this time)
(downloading now)
