@BicBasher I've just given the browser on my TV a go on YouTube, and I'm very impressed! The new style Magic Remote gives much better control - I find it far easier to point and type with. And the TV itself displays web pages really nicely, and plays back video superbly.
@Tom-R You may find it better than the LG YouTube app which isn't very good. I use it to watch Sky News in HD at 1080p which is a lot better than the 576i on Freeview or via the Now TV Box Sky News app.
