You can download the files directly by clicking on the Download links next to the player. I'm not sure what you mean by enabling download/resume? It could be that you are talking about progressive streaming versus smooth streaming (which is the default)? Can you be more specific in terms of what you want us to do?
I think I know what he means, I was downloading a bunch of HQ-WMV videos the other day from C9 to watch offline and I had to stop the download midway through, When I went to restart the downloads they all failed, had to be restart from the beginning rather than resuming from ~80%
Anyway really looking forward to watching this video, top work Charles and the team!
