There's an issue with the BT Sport website, Silverlight and the Microsoft Wireless Display Adapter (MWDA).
The MWDA uses Miracast technology and works fine with other Silverlight content when projecting the display onto my Panasonic TV. The BT Sport feed is fine on the Surface Pro that it's running from.
Unfortunately the BT Sport feed fails with the 6030 VC019 error message. I'm running the latest version of Silverlight on a Microsoft Surface Pro running IE11.
Communication with Microsoft has resulted in them looking at your website as being the issue as I have no issues with NetFlix, Sky Go or other online feeds.
Can you provide any information as why the BT Sport feed fails with the MWDA?
Not aware that Miracast was an option for the BT Sport App -
there is a stickie thread above - on Apple TV and Chromecast options
Also an HDMI conection from a PC to TV should work depending upon the performance of your PC.
The issue appears to be with BT's Silverlight implementation.
I can use Miracast to export the display from my Surface 3 to my TV using the MWDA for every Silverlight-based service I use ie: Sky, but BT Sport fails with the usual VC error.
Microsoft believe that it's BT's site that's the problem.
