divx how?

Divx is a proprietary container format that isn't supported by the tv. Depending on the contents of the container (Audio/video compression types used) there may be a variety of software products that will convert your files to a supported format.

QT Pro with Divx plug-in components is likely to be one such piece of software that will do this.
