After google search and tried many so called Tenplay downloader, I find Allavsoft works best.
I find it from this article
http://www.allavsoft.com/how-to/down...lay-video.html
According to my test, it does work great in downloading video from tenplay.
It also helps to download video from SBS on demand, abc ivew etc.
But it only allows to download five videos free free.
It has both Mac and Windows version.
Hope it also helps for you.
