Flickering is present upon stream reproduction in Videocenter (is it the one with the world99TV?) if you switch from osso-mediaplayer to mplayer, but not everytime, it's random...
Could it be that there's a problem with the LCD controller's driver? Or an hardware issue that can manifest in some particular situations? Maybe a less than perfect component matching, or not so good timings... or maybe every person that is seeing corruption had an hardware revision with some kind of problem... Just guesses...
