no run video and slow browing the menu

after successfully installed the new atv flash (black), i’ve problems with video playback through Media Player for all video files and it show me the message “Playback error - An error occurred loading this content” everything when i try to play a video file for the common extensione such as avi mpeg mp4, etc… I can see only photo from my library.

I’ve tried to use also the media plex clinet but without any good result…i’ve also another problem: i’m moving very slow into menu of appletv…what’s wrong?

Same problem here. Maybe it is because I updated the Airport Extreme firmware?

Thanks.

Hey solved, just hold down both Menu and Down on the Apple remote until the Apple TV status light blinks rapidly. These will restart ATV but prevent all settings and everything will work again.
