Just found that the new Oppo BDP-105 Universal players have a great trick up their sleeve - streaming from YouTube HD. All you do is log in, activate the TV link & then pair your tablet/smartphone to the TV.
Once this is done you can then use the player to output the tutorial vids on the big screen and the quality seems to far exceed what you get on the website.
The end result really is detailed, and even on a 50" LCD I can see & read everything.
