I think the stop/start streaming and jerky video on live sport is a much more widespread problem and the accepted solution is in fact just a work around for a particular user device.
We have watched BT sport for years via a BT TV box without any problems. My wife also used the BT Sport app on her Samsung (Android) tablet for years without any problems. She also uses the tablet without any problems to stream BBC Sport, Amazon Prime, Sky Sports via a Now TV app, and numerous TV catch up services such as iPlayer, ITV Hub, All 4 and many more. No problems with jerky video with any of these.
Then BT decide to rebrand (sell off ?) BT Sport as TNT Sport, which then can only be accessed on my wife's tablet via the Discovery+ app. I had no problem registering with Discovery+ and can watch videos and TNT Sport channels on my Windows 10 Laptop without any problems using Firefox or Chrome browsers, so my wife installed the Discovery+ app on her tablet.
This was indeed a discovery ... it is the worst app I have ever encountered, unresponsive and a terrible user interface for a programme guide making it hard to find the TNT Sport channels. To make matters 100 times worse, when you do eventually find and try to watch any live sport event, the video and audio stutter constantly and the app keeps pausing for 1 or 2 seconds (presumably buffering). Frankly it is not fit for purpose and is unusable for watching live sport.
Nothing else has changed, so this is all down to the Discovery+ app. But looking at the FAQs, help pages and forums the response is all about dodging responsibility and blaming wifi signal etc. or uninstalling then re-installing the app etc. What rubbish ! I use the same wifi for my laptop on which TNT Sport on Discovery+ works without a hitch, but perhaps not as smooth as other streaming services.
Frankly I blame BT for this fiasco and wonder why I have just renewed my Broadband and TV package on the understanding I would continue to have my previous BT Sport service, albeit rebranded as TNT Sport.
I was perfectly happy with stand-alone BT Sport channels and am very unlikely to watch anything else on Discovery+ so I would not have chosen it as part of my TV package.
Clearly the BT/TNT Sport service delivered via Discovery+ falls far short of what I signed up for, so I expect BT to sort this out or offer refunds on my TV package. I am not happy.
