iddo you are mistaken, a codec is the instructions to the computer for how to decode a divx file, it is true that some codecs come with their own stand alone players, but you don't have to use them, if you install divx 3.11 alpha it doesn't come with it's own player and will only play divx on wmp or real player (or some other video software possibly) often times when you ask for help you have to meet the repliers half way, be willing to read up on the topic, and even if their advice doesn't help you, thank them anyways, that is just common courtesy.
