Wow! You are right!
The Youtube app does NOTwork for video out, but it does work using Safari.
I also tried the Netflix app and it does work.
I really appreciate you taking the time to help me. Thank you soooo much.
I only tried the Youtube app since updating and thought the problem was iOS 6 itself.
I was trying to watch a Youtube video of my son Thomas playing Rachmaninoff's Piano Concerto No. 3.
He used the video to enter a competition to play with five orchestras in cities on the East Coast. He did get accepted to the competition which is tomorrow!! Wish I could be there, but at least I can now enjoy this video- thanks to YOU.
For your enjoyment here's the link of my son's performance: http://youtu.be/wHVxKbYCiAA
