Whenever I run the file the video wont start but instead give me an error and saying how I need an AC3 codec and stuff, so I downloaded the codec and everything and I run the video and it still wont run...why is this?
The video is most likely corrupt, but you can always open it in Windows Media Player. It's not necessary to use the Divx player. The AC3 filter is a good program. Open it from your programs and you can set your preferences.
