Thanks Gomez but before seeing your post I bought a Amazon lite £30 and was able to download the Discovery+ app and it seems to work ok . Getting back to BT to seek credit on account after they caused the issue for me .
I use the Discovery + app on an LG TV to watch rugby on TNT Sports and at times it's impossible to watch due to the stuttering. Using the BT Sports app was fine.
We are customers of BT and pay for a service from them. If BT chooses to outsource their service to a 3rd party provider that's their choice. If that service is unacceptable it's up to BT, who we pay, to fix the issue. BT must have a Service Level Agreement with Discovery+/TNT Sports, which seems obviously not being reached, by the number of compaints on the BT community about this. I renewed my contract with BT partly to be able to watch the rugby. I am now commited to a contract that provides me with an inferior service. Trying to pass the buck is unacceptable.
Hear, hear and well said @nmh64
For the live UHD rugby getting 2.0 audio via the Discovery+ app on all platforms. It is 5.1 here on all linear platforms.
Getting 5.1 on ROKU Streaming Stick 4K
Not that the picture is watchable, but the sound is 5.1 on my LG TV.
