XVid is still under heavy development with frequent changes. Some of these modifications (for now only affecting "dev" branch (unstable) builds) sometimes result in non-MPEG4 standard videos if you encoded with that codec version. If later on in development these issues have been corrected, your non-MPEG4 compliant video remains unplayable.
No fix that I'm aware of.
