When selecting BT Player on the Youview/BT TV Box I had a look at the HElp within the player.
It is in need of a through update. In particular the ACCESSIBITY and USING YOUR BT PLAYER sections are significantly out of date.
For example All about Subtitles and All about Audio Description section doesn’t cover the new Box Pro remote.
There are several inaccuracies in the Using your BT Player > All about the BT Player .. as the whistle stop tour of the main areas looks like it has been left in a time warp. this suggests that it has been overlooked for a long time.
