Hi! Due to the slow cpu and graphic chip, it's not possible to play full hd videos on the N9. But IMHO the playback of full hd videos on the N9 doesn't make any sense since the display resolution of the N9 has a resolution of 854x480 pixels only. Moreover, as the N9 has no HDMI port, you can't stream videos in more than standard resolution to a TV-set. My advice is to reencode the videos on your computer before transferring them to your N9. Use the settings described in this article: http://www.developer.nokia.com/Commu...oding_settings
