Getting mp4 from history.com

[pipo18]

Hello,
I'm trying to download episodes from History.com. I was able to download the free-for-everyone episodes with youtube-dl.
Now I want to download the ones for cable-users. For these, youtube-dl oviously states "ERROR: This content requires a valid, unexpired auth token."
I do have a login and I'm able to watch all the episodes in the browser. But I'm having difficulties to extract the m3u8 or mp4 link.

To understand how it works, I sniffed the http link when I downloaded a free-for-everyone episode with youtube-dl.
This is the original history URL:

http://www.history.com/shows/pawn-stars/season-1/episode-5

And this is the direct video URL (highest quality):

http://aepdaks3.aetndigital.com/AETN-History_VMS/BRAND_THC_PAWN_50582_CRS_2398_030_20140403_V1_S3_1800.mp4?__gda__=1466298593_02219f138b8f3073103de9d15896f55a

How did youtube-dl extract the direct video URL from the page? I was not able to find anything remotely like this in the source code or the video element.

I did find something with mp4/m3u8 via httpfox, but I wouldnt know how I would get the link out of it like youtube-dl did:

If anyone could help me how to get to the direct video URL from this free for all episode, I might be able to do the same for the cable-sub episodes.
I just saw this show for the first time and I'd like to watch it on my next trip.


TL,DR: How to get this: http://aepdaks3.aetndigital.com/AETN...e9d 15896f55a from this: http://www.history.com/shows/pawn-st...on-1/episode-5

Thanks !
