I downloaded a gumball 3000 video from gofastvideo.com heres the link to the movie http://www.gofastvideo.com/gallery/getitem/143/1/aaq.avi I tried playing the video in windows media player all I get is "windows media player has encountered an unkown error" usefull. So I open up divx open the file, it starts to play 10 mins and 33 secs later it just stops no error messages, nothing. The video is supposed to be 41:36 according to divx and g-spot. In the 4cc box of g-spot it says I need the div3 codec. I have 4 compatible codecs: DivX ;-) MPEG-4 Low-Motion DivX ;-) Hi-Res Video Decompressor DivX Decoder Filter Divx Decoder Filter I don't know why the last two show up twice but they do. I think divx is using the decoder filter codec. I want to know how to switch it to one of the other two. to see if it works. any help would be appreciated.
