I've had a lot of trouble playing You Tube videos,both from the Chrome browser and from the Google TV app. In the app,they froze and in the browser,they paused and buffered constantly. They always played well on my Mac Mini,however. Today,I went to Best Buy and bought a "range extender" to help my router send the signal farther. Now,You Tube plays very well in the browser version! Not sure if I can play HD or not,but things are much better. The app version of You Tube still plays terribly. Made a good investment today!
