Re: DivX Player

I'm not sure what the problem is. Can you describe it with some details please? If you're having trouble installing the application, please follow the instructions for Symbian at http://labs.divx.com/MobileDownload.

It's a DivX Player

DivX Mobile Player will only play DivX files. It will not play MP4, WMA or RMVB. If you need to convert these videos into DivX files, use DivX Converter available free at http://divx.com/divx
