Netflix's users have reported having no access to high definition (HD) content despite having 300Mbps fibre connections, and now Totalchannel says that Internet service providers (ISPs) are responsible for its service failing.

Several voices have claimed that the dominant telcos such as Telefónica may be hindering access to OTT platforms like Netflix - whose content offer directly competes with cable and IPTV packages - and Totalchannel - which has the Champions League rights through beIN Sports.

What began as a theory from a group of users has now become trend on Twitter, as subscribers' complaints pile up. For instance, users have been reporting that Movistar's 300Mbps connection only allows standard definition (SD) content streaming on Netflix and that by manually changing the network's domain name system (DNS) or enabling a virtual private network (VPN), the problem disappears.

And now, Mediapro's platform Totalchannel has officially stated all issues detected - and reported by subscribers - while streaming Champions League games live were due to ISP limitations, which means access to the OTT platform was not possible because Internet providers restricted the service.

"Totalchannel only delivers content to its subscribers, it doesn't own any infrastructure. Technical issues were always related to ISPs, and other OTT platforms have been experiencing similar problems while launching in Spain," the company said, clearly referring to the Netflix-Movistar issue.
