I don't think ITV hub has an HD option - could VM forum team confirm this. Also is HD an option on other devices - could anyone advise?
Re I Player, if you go into settings on the main menu and select" Video Quality" you get the options of "Best Quality" or "Standard Definition" , so presumably "Best Quality" is the HD option.
Regarding On Demand you have to go into the show you are interested in to see if HD is an Option e.g. click on "Magic City" and you will see the HD symbol after each episode. There are however a lot of series where HD is not available.
It's the same for Sky Movies, some are in HD, some are not. You have to click on the movie to find out. It's also been posted that the HD version is only available for 30 days. Is this really true VM?
