Yes, it's coming to the Wii but I don't know when, also:
- No HD
- Uses a disc
- Don't know about UK
I have the issue where sometimes on HD movies it will queue a minute or two in and seriousl downgrade my quality so I just pause it for a minute when I start the movie/show and I'm fine. Whenever you start something, just pause it for a minute and see if that fixes your problem.
