Some while ago, I was able play video clips with 1080p resolution on my N8. Now on my N9 i couldn't play either 1080p or 720p, the 720p worked but with frame lag, even when testing Youtube html 5 trial www.youtube.com/html5 when i set the video 720p the lag is SUPER.

How come is the n8 better than n9 with playback? wasn't the n9 has much CPU power and better GPU!!!
