IPlayer UHD is actually an experimental support with a restricted variety of connections at any one time as we discovered once the Euros ended up on. I do think ITVX utilizes 25fps rather than 50fps. Programmes much like the news or Coronation Avenue will look filmic/juddery when watched via ITVX. https://jav-hd48269.isblog.net/top-javhd-secrets-51879557
