VC019 is a common error code to all platforms, just meaning an error occurred when trying to start the video. It has numerous different causes on each platform.
In your particular case, the TV is just telling us "prepare failed" - a generic error meaning that the player failed to load the content. It doesn't give us any further explanation.
Our logs indicate that you issue is intermittent, and we can see some examples where a video has played ok for you, where it previously failed with VC019.
We can also see in many cases that you tried to start a video, but our logs show no attempt by your TV to download the video from us.
Together, these signs suggest an issue with the network connection.
How is your TV connected to your internet? Do you see any issues at all with other apps on your TV? When you next see this error, could you immediately try another streaming app on the TV? What quality of video are you getting from other apps? Could you use the device checker within the BT Sport app (accessed from the cog in the top right) to test what it believes your connection speed to be?
We have also had some success with customers calling the Samsung help desk for this issue - they're able to see more information about what is happening on your TV. Customers have told us that Samsung have managed to fix the issues for them remotely.
Our logs aren't indicating a widespread issue, however usage is low outside of the football season so it's hard to prove anything one way or the other.
