Ordered Aiseesoft mxf converter under the auspices of a 30-day money back guarantee. Found that none of the files rendered with the software (mp4, wmv, avi at various specifications) would sync with Pluraleyes in my video editor. I requested a refund after a weekend of troubleshooting their software. I've wasted a substantial portion of my week explaining the situation about a dozen times to different people in their "support team." They've refused to issue refund. The software is a joke and their return policy is, as well. Please avoid at all costs.
