We have been having more and more problems with xmbc and its offshoots for years now. The Cloud seems to have come to the rescue... What is supposed to be a one at a time download, or stream, has been taken and corrupted by these types of (I say this loosely) "Library's or Repository's." It causes others to loose out on bandwidth.
We have no association with these programs, and truth be told, we are not very fond of them, as they cause problems with normal users. If you downloaded a link singly, I am sure it would work fine. The Cloud now sees the "Scraping" that these programs do as an attack, and does its job and protects the site.
