In the last week or so I have started having problems when watching BT sports using Chrome or Microsoft Edge. This method has worked fine for me for a few years now so something has changed. The stream seems to have a problem of some kind, keeps buffering, stuttering etc. My broadband speed is 200mB/s so no bandwidth problem. I have found a solution to this but would like a fix. If I use Firefox web browser the stream is rock solid and works fine without and stuttering. This seems to imply that Chrome or Edge are managing the stream differently. By the way I also stream using Sky Go and that works fine.

After messing around with chrome, extensions and many other things it turns out that video acceleration was the culprit. Turning Vid Acc off fixed the stuttering problem. You can turn off Vid Acc from the chrome settings menu, then the option is hidden in the system tab "Use Hardware acceleration when available"
