Duke: ABR (average bit rate) is low at 2260Kbs vs TV1 at 8060kbs
We pay money each month subscribing to Rialto which we rate as a premium indi movie channel but it is only braodcast at 2260kbs - and it shows!.
Vodafone needs to sort this with Sky to get the quality improved!
I apologise for the delays responding to your post.
Thanks for your feedback - We will pass this onto the relevant teams to investigate further and see if there's anything that we can do to improve the quality of the Duke channel.
