I get acceptable results with Konttori's Media Converter, about on par with my 770 in its latter days. However, it appears the latest version of Media Converter has become a lot more picky about the input files: Quite a lot of Divxfiles end up with a "fail" (irritatingly always right at the end, after half an hour of furious converting going on) and won't play anywhere. Unfortunately, the only other decoder I've got, PocketDivXEncoder, refuses to produce a file that the N800 will play.
