IM TRYING TO PLAY A MOVIE AND DIVX TELLS ME I NEED A NEW CODEC
IT SAYS VIDEO DATA IS FOURCC CODE “O”
WHAT IS CODE “O" 
this is the fake codecs
sorry to tell you this man but you got a fake file,
let me guess you got it on kazaa!!!!
Download “divx_3.11alpha”, “XviD-Dec-160703” and “xvid112502” to update your player.I had that problem, but now it’s ok.If you need some help send me an e-mail.
A FourCC of “0” means there’s no Video stream.
It is definitely a fake file: http://www.divxmovies.com/faq/#4.3
Please note that there doesn’t exist any video codec that uses the FOURCC code 0. If... with the FOURCC code 0 it’s a fake... file and you won’t be able to watch it.Feedback
Yeah I have the same problem with videos I record with my Digital Camera....Anyone know how I can like fix it? ?:(
