Since using the News Multiscreen facility on Freeview, I have found that the thing that annoys me is that when exiting from the application (that is, pressing the Red, Text or Quit buttons on your remote), you are taken to News 24, rather than going back to the channel you selected the Multiscreen application from (as it does on the DSAT version).
Whereas when the Interactive programmes are on, you can Quit from the interactive application you are using (usually carried on 701/702), and can return to the channel that you was watching at any time.
