Trying to download "The Legend of Korra" from "http://nick.walla.co.il/" fails (running verbosely):

I'm seeing the same issue (I tried http://nick.walla.co.il/?w=//2772660). I'm assuming that nick.walla.co.il and vod.walla.co.il use the same software (it definitely looks similar), so much of the walla.py code should be relevant, but I am not familiar enough with what walla.py is doing to be able to fix it.

Oh, and even for vod.walla.co.il, something isn't really working: I tried
youtube-dl http://vod.walla.co.il/episode/2597978/inspector-gadget/episode-10
and get an error:
