That's a common misunderstanding. youtube-dl supports about a
quazillion sites. It's a quite generic tool to save you from parsing
through HTML, JSON, JavaScript, and so on - if it happens to work, or
if someone has put their knowledge into an extractor. ABC Australia
refuses to serve their videos to me (outside of Australia), but there's
an example ABC link in the program's source itself. Here, this is what
happens (sorry, on Windows, my Unix machine is off):

c:\Users\mbarsnick\Downloads>youtube-dl.exe http://www.abc.net.au/7.30/content/2015/s4164797.htm
[generic] s4164797: Requesting header
WARNING: Falling back on generic information extractor.

That was not iview though - it may or may not work for iview. Probably
(python-iview has been taken down, BTW.)
