There seems to be alot of confusion about this online so in case anybody here is wondering, or if they google search in, The Zen V Plus does not support native divx according to a detailed review from PC Mag.

This confusion is also enhanced by the CNet review incorrectly stating it does support native divx files.

Converted video files from Creative Video Converter are in a proprietary DIB format (128 by 96 pixels) but at only 12 frames per second, which makes longer clips very fatiguing to watch. The software can convert most common video formats, including AVI (DivX and XviD), WMV, MPEG-2, MPEG-4, and QuickTime (MOV). It can also convert DVR-MS files, which is content that's recorded on a PC running Windows Media Center Edition. Creative Video Converter is easy enough to use, though it would be nicer if the device could handle WMV files, which could be converted right in Windows Media Player.
