I was underwhelmed by ATV2's YouTube. For starters, you only get a partial list of your subscriptions. You don't get automatically logged onto your account, you have to scroll down and select it. And the quality sucks! it only displays content at the lowest resolution regardless if the content is HD. The XBMC YouTube displays ALL of your subscriptions It logs you into your account as soon as you click on it And most importantly, plays HD content. One can select to display 1080 or 720, but this option is missing under ATV's native YouTube implementation, which is a joke. Unless there's a setting that I missed, if so then the joke's on me... I lose.
