DivX Author is the name of new program launched at CES by, well, DivX of course - the company that specialises in software to heavily compress video to save storage space and cut down bandwidth, without throwing away picture quality. What the app does is let you add DVD-like features to squashed down files.

The appropriately-named Windows program, which can do the compression itself, allows the addition of chapter-points, menus, multiple soundtracks and multiple subtitles.
