There are three possibilities here:
The first is that you may not have the latest codecs (encoders/decoders) on your system, the other possibility is that there is fault in the file.
If this is not the solution, there may be a problem with the file, please use a converter to convert the file in to a different format.
Most converters will fix known errors as they do the conversion
Otherwise There may be one or more XSitePro application file that has become scrambled.
